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.
UHMW-PE filled with glass increases hardness and improved the coefficient of thermal expansion particularly suited to combat flow problems experienced in the bulk material handling industry. Superior abrasion resistance properties makes this material ideal for use as liners in the handling of coal, sand, gravel, phosphate and fertilizer.
