UHMWPE Pipes

UHMWPE Pipes(Ultra-high molecular weight polyethylene pipe)

UHMWPE Pipes introduction

UHMWPE Pipes, Ultra-high molecular weight polyethylene, be named as marvelous plastics . It is a kind of engineering thermoplastics with more than 2 million viscosity-average molecular weight, under the polymerization of ethylene, butadiene monomer in the catalyst. Ultra-high molecular weight polyethylene pipe has the superior performance such as very high wear resistance, impact resistance, excellent resistance to internal pressure strength, resistance to environmental stress cracking, eminent self-lubricating, anti-adhesion, the unique low temperature resistance, good chemical stability and so on, and it is widely used in metallurgical mines, electric power, petroleum, natural gas, textiles, paper making, food, chemical industry, machinery, electrical and other industries.
