UHMWPE is an ultra-high molecular weight polyethylene with an average molecular weight of more than two million. UHMWPE has more excellent properties than HDPE, such as extremely high wear resistance, high impact resistance, good self-lubricating ability, and anti-aging. It can still maintain good toughness and mechanical strength at liquid nitrogen temperature. Excellent chemical and mechanical properties make UHMWPE sheet widely used in electric power, marine, coking, coal, paper, textile, chemical and other industries.
