A subset of the thermoplastic polyethylene, UHMW (aka UHMW-PE) is characterized as one of the miracle polymers of the 20th century, UHMW’s incredible durability and versatility make it a favorite among engineers and designers in nearly every industry worldwide. The key is UHMW’s incredibly long molecular chain, which give UHMW a host of exceptional attributes such as high abrasion resistance, low coefficient of friction and unparalleled impact resistance, even in cryogenic environments. Ideal for use in applications where wear and friction play a part. Industries such as material handling, food processing, automotive, railroad, agriculture, medical, printing and packaging all have numerous applications where UHMW coatings and materials can provide benefits and enhance efficiency and productivity.

Natural and reprocessed grades are still the most common. UHMW modified to meet particular application requirements through formulations with additives and fillers create special and premium grades with the enhanced desired property. Following are a few of the most common premium grades: Glass Filled, Cross-linked, UV Stabilized, Static Control: Anti-Static, MoS2 filled, Oil filled, Flame retardant and Heat Stabilized.
