A subset of the thermoplastic polyethylene, UHMW (aka UHMWPE) is characterized as one of the miracle polymers of the 20th century. UHMW’s host of exceptional attributes such as high abrasion resistance, low coefficient of friction and unparalleled impact resistance, even in cryogenic environments, make it a favorite among engineers and designers in nearly every industry worldwide. UHMW modified to meet particular application requirements through formulations with additives and fillers create special and premium grades with the enhanced desired property.

Anti-static UHMW is an ideal material to use when potentially volatile conditions exist, such as those in grain elevators and munitions plants, effectively safeguarding against static discharges. In addition, it resists heat and protects robotics and other products that are sensitive to dust accumulation and electrical charge buildup.

Static Disspative UHMW eliminates static build-up problems, meets FDA and USDA guidelines for food contact and exhibits a longer wearing, lower coefficient of friction sliding surface than stainless steel.

Conductuve UHMW adds carbon powder to the resin, increasing the conductivity of UHMW to control static electricity formation or conduction.
