Polyurethane Elastomer's Place in Food Processing By: Chase Brett
The food processing industry has always used a myriad of food grade thermoplastics in order to satisfy complex application requirements, while remaining safe and detectable. Some plastics are used interchangeably, while others have special properties that cannot easily be replaced. What if many critical material properties could be fulfilled by a single material? Polyurethane elastomers are recently replacing traditional thermoplastics in food processing applications due to their low tooling costs and wide range of properties, ranging from rubber-like to plastic-like.
​
Traditional plastics have always been chosen based on one or two properties, at the expense of the other critical properties, leading to a shorter part life cycle, or an underwhelming application performance. A few of the key physical properties engineers must keep in mind while selecting materials for a food process are cost, detectability, chemical resistance, heat resistance and flammability, abrasion resistance, weight and rebound rate. There are plenty of other properties to consider, however these are just some of the complex application requirements a process, quality, and mechanical engineer might consider.
Until recently, the food industry has relied on a wide selection of materials, from UHMW and POM, to PP and nylon, each selected to maximize one or two properties, but forgoing other critical properties. One example of this is the commonly used ultra-high molecular weight polyethylene (UHMW-PE). UHMW-PE is a great material chosen for food processing due to its abrasion resistance, X-ray ability and its food safety capability. However, due to a low melt flow, the material often needs to be machined to create complex shapes. This increases labor costs and creates extra waste.
​
The ability to reduce routing steps marks one of the main reasons engineers are making the shift to polyurethane. The cast process that polyurethane demands allows for the production of a finished part, similar to injection molding, without the additional cost of complex tooling or expensive machinery. This means polyurethane is cost effective as you scale and the materials it’s replacing reflects this. Polyurethane elastomers are now replacing UHMW, HDPE, nylon, POM (acetal) and other similar thermoplastics in favor of the reduced tooling cost and versatile durometer range. Polyurethane elastomers offer a wide range of physical properties including high impact resistance, excellent rebound rate, good tear strength, good chemical resistance and high abrasion resistance.
​
Polyurethane elastomers can also be formulated to meet specific food grade requirements, such as FDA compliance and antimicrobial properties. Additives can reduce or increase abrasion resistances, are anti-static and offer all three major forms of detection; from color detection and X-ray, to metal detection. The material also allows for bonding to other materials such as metal, plastics or rubbers. This even allows companies to reclaim the metal bonded to polyurethane at the end of a part’s life cycle and rebond polyurethane to the same reclaimed metal.
The number one characteristic of polyurethane that is fueling this new wave of change is the material’s hardness range or durometer. Polyurethane elastomers belong to a category of synthetic rubber that exhibits plastic characteristics. This allows parts to range from being as soft as a gummy bear, to as hard as a bowling ball. This range allows for the fine tuning of many of the critical physical properties mentioned earlier. With this unique characteristic, the same mold can make parts of the same dimensions, but with very different physical properties. This is highly useful in not only production, but during the prototyping phase as well.
​
Metal Detectable Polyurethane Rubber used in food processing
In terms of cost-effectiveness, polyurethane elastomers have a lower tooling cost compared to traditional thermoplastics. This is because polyurethane elastomers are typically cast into shape rather than machined, reducing labor costs and minimizing waste. Though polyurethane is famous in cast, polyurethane is not restricted by this, as mass production can be achieved in cast processes, and thermoplastic urethanes are also available if a company needs an even higher throughput that is only achievable through injection molding. Furthermore, polyurethane elastomers have a longer part life cycle than many traditional thermoplastics, reducing replacement costs and improving overall application performance.
Manufacturing processes have traditionally been limited by the material chosen for the application. Injection molding is the most common among these but comes at the expense of very high tooling costs and lead time. Other manufacturing processes, such as compression molding, may be used but has geometric limitations and generally produces a lower quality finish. This is the process used for UHMW components and other rubbers. Polyurethane uses a liquid cast process that produces engineering grade components with a low upfront tooling cost and shorter lead times.
In terms of heat resistance, polyurethane elastomers can be formulated to withstand high temperatures, making them suitable for use in applications such as ovens. This places polyurethane operating temperatures below engineer grade plastics such as PEEK, PEI or PPS, but above most POM, PP, PMMA, and on a similar level as nylon. Polyurethane can perform in consistent temperatures of 250 °F and up to 300 °F with specialized formulas. Additionally, they have low flammability and can meet various flammability standards.
​
Polyurethane does struggle to perform with applications experiencing high exposures to steam or select chemicals. However, most food grade wash down processes can expect to see hundreds or thousands of cycles before parts break down. Polyurethane parts can even be submerged under water for years and continue to perform. The versatility of polyurethane elastomers allows them to be used in a variety of food processing applications regardless of size or complexity, such as conveyor belts, sprockets, gears, dividers, seals, gaskets, rollers and more.
​
In summary, the use of polyurethane elastomers in the food processing industry offers a range of benefits over traditional thermoplastics, including cost-effectiveness, versatility and improved application performance. As a result, more engineers and manufacturers are turning to polyurethane elastomers as their material of choice for food processing applications in order to improve part life, reduce tooling costs and increase available detection methods.

Unlocking the Potential of Thermoset Polyurethane Elastomers:
Unique Sterilization and Antimicrobial Properties in the Medical Industry By: Chase Brett
I
In the fast-evolving world of medical devices and healthcare technology, materials that combine durability, biocompatibility and resilience under harsh sterilization methods are in high demand. Thermoset polyurethane elastomers (PUEs), often overshadowed by their thermoplastic counterparts, are emerging as a superior class of materials offering exceptional performance under sterilization stress and novel antimicrobial capabilities. Their growing relevance in surgical tools, implantable devices, diagnostic systems and wearable medical technologies is no coincidence.
This article explores the unique sterilization resistance and inherent or engineered antimicrobial performance of thermoset polyurethane elastomers—and why they are quickly becoming indispensable to medical manufacturers seeking longevity, compliance and performance in demanding environments.
​
What Makes Thermoset Polyurethane Elastomers Unique?
Polyurethanes are widely used across industries, but thermoset PUEs differ significantly from thermoplastic polyurethanes (TPUs) in both structure and performance.
Whereas TPUs can be remelted and reshaped, thermoset PUEs are chemically crosslinked during curing, resulting in a three-dimensional, irreversible network. This structural distinction gives thermoset PUEs:
-
Higher thermal stability
-
Better chemical resistance
-
Superior mechanical resilience under cyclic stress
-
Enhanced performance under sterilization exposure
​
Moreover, thermoset polyurethanes can be engineered across a wide hardness range (30A to 85D), and offer excellent flex-fatigue, abrasion resistance and low compression set, all of which are vital for components used in critical healthcare environments.
​
The Challenges of Sterilization in Medical Manufacturing
Medical devices must be sterilized to eliminate bacteria, viruses, and other pathogens before use. Common sterilization methods include:
-
Autoclaving (steam sterilization at 121–134°C)
-
Ethylene oxide (EtO) gas sterilization
-
Gamma radiation (25–50 kGy)
-
E-beam or electron beam sterilization
-
Hydrogen peroxide plasma (low-temperature gas plasma)
​
These processes are harsh on materials, often causing:
​
-
Embrittlement or softening
-
Color degradation
-
Loss of mechanical integrity
-
Surface cracking or delamination
Traditional TPUs, silicones and polyolefins often suffer from degradation under gamma or high-temperature steam. This is where thermoset polyurethanes shine.
​
Sterilization Resistance: Thermoset PU’s Core Advantage
Thermal Stability
Thermoset PUEs can be formulated to resist autoclave cycles up to 135°C without significant degradation in hardness or tensile strength. Chain orientations that promote density play a key role in withstanding repeated high-temperature cycles.
Radiation Resistance
Whereas many plastics degrade or discolor under gamma irradiation, thermoset PUEs — show excellent resistance to radiation-induced breakdown. Aromatic systems may yellow but maintain mechanical properties better than many commodity plastics. Some additive colors can furth its resistance.
​
Low Extractables & Leachables
Post-cure thermoset systems have lower risk of monomer migration, plasticizer leaching, or degradation byproducts. This minimizes cytotoxicity and contamination in sterile environments, an increasingly important concern for FDA Class II and III devices.
Dimensional Stability
Under repeated sterilization, dimensional accuracy can degrade in many traditional materials. Thermoset PUEs maintain tight tolerances and form retention, especially important for gaskets, seals, surgical tool grips and diagnostic housings.
​
Antimicrobial Potential: Surface Protection Built In
While sterilization addresses pathogens before device use, antimicrobial properties ensure ongoing defense during use. Thermoset PUEs can be engineered for passive and active antimicrobial performance in several ways:
​
Incorporation of Antimicrobial Additives
Thermoset polyurethane can be loaded with:
-
Silver ions or nanoparticles
-
Zinc oxide or copper compounds
-
Quaternary ammonium salts
-
Organosilane-based antimicrobials
​
These agents either leach slowly from the surface or act as contact biocides, disrupting microbial membranes. The crosslinked matrix slows diffusion and offers controlled, sustained release profiles.
Non-leaching Surface Modifications
Reactive surface grafting techniques can bond antimicrobial moieties directly into the polymer backbone, preventing leaching and maintaining permanent biofilm resistance. This is valuable in implantables, catheters and long-term-use equipment.
Smoothness & Hydrophobicity
Thermoset PU coatings can be engineered to resist bacterial adhesion through low surface energy and high hydrophobicity. Some variants mimic Lotus-effect surfaces, making it difficult for microbes to anchor and multiply.
​
Applications in the Medical Industry
Thermoset polyurethane elastomers are already making an impact across various medical device categories:
​
Catheter and Endoscope Components
With tight tolerances, chemical resistance, and surface clarity, thermoset PU liners or distal tips offer bio-inert pathways that can withstand sterilization.
​
Diagnostic and Analytical Devices
Lab-on-chip modules, flexible diagnostic seals, and microfluidic ports benefit from low extractables and sterilization durability.
​
Surgical Grips and Handles
Textured, ergonomic handles made from 70A–95A PUEs offer resistance to repeated steam/gamma cycles and glove-friendly grip, especially under blood or saline exposure.
​
Implantable Device Components
Select medical-grade thermoset PUs show long-term biostability and hemocompatibility, suitable for leads, sleeves and encapsulants.
​
Antimicrobial Pads, Seals and Mats
Molded antimicrobial PU mats are used in operating rooms, diagnostic tables and sterile field dividers, leveraging both mechanical durability and built-in microbial resistance.
​
Challenges and Considerations
While promising, thermoset PU use in medical settings requires:
-
Precision tooling for cast molding. Tooling is less expensive than a traditional injection mold but can still be a significant investment depending on design complexity.
-
Post-curing protocols to ensure full crosslinking and leachables control
-
Material traceability and lot certification for regulatory compliance
-
Careful additive selection to balance antimicrobial efficacy and biocompatibility
The Future Outlook
As the demand for safe, long-lasting, and sterilization-tolerant medical devices increases, thermoset polyurethane elastomers are positioned to become the material of choice for challenging applications.
Their tunable chemistry, crosslinking architecture, and ability to integrate antimicrobial functionality offer a unique trifecta that aligns with FDA regulations, hospital performance needs and patient safety requirements.
Expect increased usage in:
-
Wearable biosensors and patient monitoring tools
-
Advanced wound care materials
-
Surgical robotics
-
Drug delivery enclosures
​
Conclusion
Thermoset polyurethane elastomers represent an underutilized but high-potential material class in the medical field. Their ability to endure rigorous sterilization cycles, maintain mechanical integrity and incorporate antimicrobial properties, make them highly valuable, and they may be the next frontier in safe, sterile and smart medical device design. ​

​
Beginnings of plastic in aerospace
Plastics were not used in the aerospace scene until World War II, when leaders pushed for military aircraft to become lighter, more durable and more agile. As metal became scarcer in America, plastics and rubbers found their way into flagship aircraft, giving them a cutting edge on the enemy.
​
Plastics allowed aircraft to be lighter and more resistant to environmental factors, enhancing durability in combat conditions. Early applications included non-critical parts like interior panels, insulation and components in the cockpit. Their adaptability, however, quickly saw them expanding to external parts and even windows, where acrylics replaced glass, offering better impact resistance and transparency while reducing weight. These advances in plastic applications set the stage for their continued role in aerospace, with innovations developed during the war laying the groundwork for the industry’s ongoing reliance on plastics in the following decades.
​
Why do plastics fit?
Plastics look to solve some of the most significant barriers to space exploration and travel. Weight reduction is a crucial aspect of space flight, and plastics with low weight and high resilience look promising in filling the gap needed for efficient space flight. Space is also a hostile environment with problems such as extreme temperatures, radiation and micrometeoroids. Plastics, engineered specifically for aerospace applications, offer resilience in these harsh conditions. Plastics can also be recycled, which is crucial when astronauts are in places where raw materials are scarce, such as the moon and Mars.
​
The future of plastics in space flight
As space agencies and private companies pursue ambitious plans for lunar bases, Mars missions and interstellar travel, the role of plastics is becoming increasingly essential. Known for their versatility, light weight, durability and affordability, advanced plastics are being integrated into nearly every aspect of modern spacecraft. From reducing weight and fuel consumption to enabling sustainable, long-term missions, plastics will transform how we design, build and operate spacecraft.
​
Theoretically, it takes about 10 pounds of fuel for every 1 pound of cargo to be sent into Low Earth Orbit (LEO), making a payload-to-fuel ratio of about 10%. In the real world, that percentage is much lower. SpaceX’s Falcon 9 rocket, one of the most efficient rockets to date, averages about 17 pounds of fuel for every 1 pound of cargo to LEO. This is a payload-to-fuel ratio of about 5.8%. However, reducing the weight of the overall structure of the rocket while maintaining structural integrity allows for more payload. The name of the game in the aerospace industry is weight reduction, and plastics serve a critical role in achieving this goal.
SpaceX’s Starship SN16 aims to enable interplanetary travel from its launchpad in Boca Chica, Texas.
​
Plastics are significantly lighter than metals, which helps reduce the overall weight of aircrafts and spacecrafts. This reduction in weight leads to lower fuel consumption and increased efficiency. Despite being lightweight, many plastics offer high durability and resistance to wear and tear, making them ideal for various aerospace applications. This lightweight nature of plastics contributes to fuel efficiency and the ability to carry more payload or passengers, increasing the operational capacity and economic viability of aerospace missions. As plastics become stronger and lighter, aircraft and spacecraft components will transition from metal to plastic.
​
High-performance thermoplastics and thermoset resins can be formulated to endure extreme temperature fluctuations, from the intense heat of reentry to the cold of outer space. They also resist corrosion and chemical degradation, allowing them to last longer in environments where traditional materials might fail.
​
Certain plastics are radiation-resistant, an essential feature for protecting structural and electronic components from cosmic rays and solar radiation. These plastics will help extend the operational lifespan of spacecraft and make them suitable for deep-space missions, where exposure to high radiation levels is unavoidable.
​
Furthermore, plastics’ insulating properties are ideal for shielding sensitive electronics and life-support systems. Plastics can provide a protective barrier for wiring, instruments and control systems, helping to prevent electrical shorts and other failures that could compromise mission safety. They can also serve as efficient insulators for heat and electrical currents, a valuable property for managing temperature fluctuations in space and protecting equipment from harmful electrical surges.
​
In manned missions, plastic materials will be vital to creating safe, livable environments for astronauts. Lightweight plastic composites can insulate walls in crew habitats, protecting occupants from radiation and temperature extremes. Plastics can also be used to construct spacesuits, airlocks and life-support systems, helping astronauts maintain safe atmospheric pressure and temperature.
​
Plastics also offer a cost-effective alternative to traditional aerospace materials, which are generally easier to produce, mold and transport. Lower costs make space exploration more accessible for private companies and national agencies, helping drive innovation and increase the frequency of missions. Furthermore, developing sustainable plastic recycling methods could be essential for reducing waste and reusing resources on extended missions.
In a future where lunar or Martian colonies exist, recycling plastic waste into new materials could provide a continuous source of raw materials for manufacturing essential components, tools and equipment. This closed-loop system would help reduce reliance on Earth-based resupply missions and support self-sustaining human habitats on other planets.
​
Research into advanced plastic materials is paving the way for innovations that could redefine spacecraft maintenance and durability. “Smart” plastics with embedded sensors can monitor structural integrity in real time, allowing operators to detect weaknesses or damage. This capability is best suited for deep-space missions, where human intervention may not be possible. Self-healing plastics, another promising development, can repair micro-cracks or punctures caused by debris, helping to maintain the structural integrity of spacecraft automatically.
​
These futuristic materials could eventually be used in spacecraft hulls, habitats and spacesuits, reducing maintenance requirements and improving safety. By enabling spacecraft to adapt and respond to their environment, smart and self-healing plastics could play a critical role in ensuring the success of long-duration missions and deep-space exploration.
​
In summary
As we continue to explore the cosmos, plastics will be fundamental in creating efficient, reliable and resilient spacecraft capable of supporting human life. With their lightweight nature, durability and adaptability, plastics offer unique advantages for spaceflight that make them irreplaceable. In the coming years, developing new plastic materials tailored to the needs of space exploration will drive progress in the industry, enabling missions that would have once been impossible.
​
From sustainable habitats on the moon to Mars colonies and beyond, plastics empower humanity to take the following steps into the final frontier. As material science evolves, plastics will remain at the forefront of space innovation, transforming how we design, build and sustain life far from Earth. The future of spaceflight is taking shape, and plastics will play a key role in making interplanetary exploration and colonization a reality.
How Custom Polyurethane Seals & Gaskets Keep Equipment Running
How Custom Polyurethane Seals and Gaskets Keep Equipment Running
Every piece of heavy equipment relies on one thing to stay productive: reliable seals and gaskets. These small parts do big jobs—keeping fluids where they belong, blocking dirt and debris, and holding pressure under tough conditions. When seals fail, equipment fails. That’s why more industries are turning to polyurethane instead of traditional rubber or plastic.
​
Why Rubber and Plastic Fall Short
Rubber gaskets often swell, crack, or lose flexibility after exposure to heat, oil, or chemicals. Plastic seals can become brittle and break under pressure. Both options can leave equipment exposed to leaks and costly downtime.
Polyurethane elastomers offer a better solution. They maintain strength and flexibility in tough environments, helping equipment last longer between repairs.
​
The Polyurethane Advantage
1. Chemical Resistance
Polyurethane seals resist swelling and softening in oils, fuels, and industrial fluids that quickly break down rubber.
2. Abrasion Resistance
In agriculture, mining, and construction, seals are exposed to dust, sand, and grit. Polyurethane resists wear and keeps sealing surfaces intact.
3. Long-Term Flexibility
Unlike plastics that snap or rubber that hardens, polyurethane stays flexible for a longer period—keeping your equipment protected.
​
Applications in the Southeast U.S.
Across the Southeast, industries rely heavily on equipment in agriculture, forestry, marine, and construction. In these sectors, seals and gaskets take a beating every day. Custom polyurethane seals help reduce downtime during critical planting, harvesting, or building seasons.
Some examples include:
-
Hydraulic seals for tractors and harvesters
-
Gaskets for marine engines and pumps
-
Dust seals for construction machinery​
​
Custom-Molded for Your Needs
Off-the-shelf seals rarely fit perfectly. Polyurethane allows for custom designs tailored to your exact application—whether you need:
-
Extreme temperature resistance
-
Special hardness ratings
-
Unique shapes or sizes
​
Custom polyurethane seals ensure your equipment gets the longest possible service life.
​
Conclusion: Stronger Seals, Less Downtime
Seals and gaskets may be small, but they have a big impact on productivity. By choosing polyurethane over rubber or plastic, manufacturers gain parts that last longer, reduce leaks, and cut maintenance costs.
Polyurethane vs. Rubber:
The Smarter Choice for Equipment
Polyurethane vs. Rubber: Which Lasts Longer in Heavy Equipment?
When equipment shuts down, it usually means lost time, lost money, and frustrated workers. One of the most common reasons for downtime is simple: parts wear out faster than expected. For industries that rely on heavy equipment—mining, agriculture, construction, and material handling—the choice of material can make all the difference. The big question many manufacturers face is this: should you choose polyurethane or rubber?
​
Durability Under Pressure
Rubber has been used for decades, but it often struggles in high-stress conditions. Polyurethane elastomers, on the other hand, are designed to handle repeated impacts, heavy loads, and constant abrasion. This makes them the go-to choice for parts like:
-
Conveyor belt rollers in mining operations
-
Wheels for forklifts and warehouse equipment
-
Agricultural harvester components
Polyurethane’s toughness means fewer breakdowns, fewer replacements, and more uptime.
​
Better Resistance to Chemicals and Oils
One weakness of rubber is that it swells, cracks, or becomes brittle when exposed to oils, fuels, or harsh industrial chemicals. Polyurethane resists these challenges much better. For industries that run hot, wet, or dirty—such as construction and marine—this chemical resistance makes polyurethane a smarter and longer-lasting option.
​
Abrasion Resistance That Saves Money
In abrasive environments like quarries, farms, or manufacturing plants, materials grind against equipment every day. Rubber parts wear away quickly, while polyurethane components hold up far longer. That longer lifespan means you buy fewer replacement parts, spend less on labor, and cut downtime. Over time, polyurethane often costs less than rubber—even if it costs more up front.
​
Regional Advantage for the Southeast U.S.
Across the Southeast, industries like agriculture, forestry, and construction run year-round. Every day of downtime during planting, harvesting, or peak building seasons comes at a high cost. Polyurethane seals, gaskets, wheels, and custom-molded parts help manufacturers in the region keep equipment running longer, avoiding costly delays.
​
Custom Engineered for Your Application
Unlike standard rubber parts, polyurethane can be engineered for your exact needs. Whether you need:
-
Hardness tailored for high loads,
-
Added abrasion resistance,
-
Or a custom-molded design, polyurethane can be customized to perform better than off-the-shelf rubber solutions.
​
Conclusion: The Smarter Long-Term Choice
Rubber may still have its place in some applications, but for heavy-duty equipment that must keep running in harsh environments, polyurethane is the stronger, longer-lasting, and more cost-effective solution.
