Known for its outstanding abrasion resistance and high impact resistance, Ultra-High Molecular Weight Polyethylene (UHMW-PE) has countless applications across nearly every industry worldwide, and is used to make everything from mining chute liners and farm equipment skid shoes to snowmobile skis and snowplow cutting edges.
UHMW-PE is a linear polyethylene with an extremely high molecular weight, making it far superior to any other thermoplastic for wear resistance, and by far one of densest polymers available, outperforming even carbon steel for wear applications. No other material can match UHMW’s slickness and abrasion resistance
Agriculture Applications for UHMW
Our May Wes division pioneered the application of UHMW poly in the ag industry. UHMW is used to make G4 Stalk Stompers to protect combine tires and tracks, skid shoes, auger trough liners, and much more. May Wes products have been featured by the Minnesota Millennial Farmer. See www.maywes.com.
Our May Wes Manufacturing Division pioneered the application of UHMW poly in the agricultural industry back in the early 1970s and we have been working with this exceptionally slick and durable polymer ever since. Put our UHMW expertise to work for you for your next plastic compression molding or plastic fabrication project.
UHMW is an Ultra High Molecular Weight Polyethylene with a molecular weight between 3.1 and 11 million, making it one of polymer materials with the highest molecular weight. The high molecular weight contributes to its exceptional properties, such as high strength, impact resistance, and low friction.
UHMW-PE is incredibly impact resistant. Professional sno-cross racers have been pounding moguls on UHMW C&A Pro snowmobile skis for nearly 30 years.
UHMW poly is extremely resistant to abrasion, and holds up better than steel, hardwoods and other polymers in abrasive applications. It’s been used in gritty bulk material handling and agricultural applications for decades.

UHMW poly is a very slick, self-lubricating non-stick material with a coefficient of friction (dynamic) of 0.12. This allows materials to slide right over it without building up, making UHMW-PE an excellent choice for any application that requires a slippery surface to prevent caking. Oil and grease can be eliminated from bearing applications, making UHMW components a popular choice for commercial food handling and bottling applications.
UHMW-PE absorbs virtually no water and withstands many corrosive chemicals – These characteristics make UHMW poly an excellent choice for the food, beverage, pharmaceutical and chemical industries as well as for water treatment applications.
Natural virgin UHMW-PE is USDA and FDA approved for direct food contact.
UHMW-PE is an excellent choice for cold-weather applications. Snowmobilers prefer UHMW snowmobile skis for their durability and slick surface, and cities and contractors often install a UHMW poly cutting edge to snowplows and skid steer buckets to protect paved surfaces from plow damage. UHMW can withstand sub-zero temperatures to -450° (Roechling Polystone® M UHMWPE):
UHMW-PE has a melting point of 320°F (160°C).
UHMW-PE is eight times lighter than steel but outwears carbon steel for abrasion resistance by 10 to 1.
UHMW will save you time and money on maintenance. UHMW-PE reduces corrosion and wear so parts last longer. It also is self-lubricating, eliminating time-consuming lubrication requirements. Slick UHMW-lined chutes are far easier to keep clean than metal.
UHMW’s slick property helps reduce energy costs by reducing friction and thermal loss. Conveyor belts operate more efficiently because product moves more freely, and farm equipment outfitted with poly passes through fields with less resistance, reducing fuel costs.
UHMW poly can be used to protect expensive equipment from wear and tear, and to replace worn metal parts for a fraction of the cost.
