UHMW-PE is the engineering thermoplastic that the average molecular weight greater than 2 million which is composed under the action of ethylene, butadiene monomer in the catalyst. Its comprehensive performance can work in the condition of - 269 to 80℃ for a long time, wear-resisting, low temperature resistance is known as "amazing" engineering plastics. UHMW – PE engineering plastics pipe technology has matured gradually in China, more and more projects start to use this kind of wear-resistant material, and it becomes a new engineering thermoplastics with moderate price and excellent performance.
