UHMWPE (Ultra high molecular polyethylene) is a linear structural polyethylene (PE) with viscosity-average molecular weight of more than 1,000,000 (ordinary polyethylene molecular weight is only about 200,000~300,000). The high relative molecular weight, which has given its extraordinary performance, and makes it a new type of high-performance thermoplastic engineering plastics. Due to its high molecular weight, UHMWPE almost has integrated the advantages of all kinds of plastic, with common polyethylene and other engineering plastics incomparable corrosion resistance, impact resistance, self-lubrication, corrosion resistance, low temperature resistance, health non-toxic, no adhesion, non-water-absorption and other comprehensive performance. Especially in the transmission of solid particles, powder, slurry and gas, UHMWPE has shown a unique superiority, thereby it is called as "amazing plastic".
