It combines the superior performance of most plastics, impact resistance, low temperature resistance, abrasion resistance, chemical resistance, self-lubricating, absorb impact energy, which is the highest value currently six properties in plastics has, in recent years, this new plastic products are widely used in Europe and the United States, demand is growing. UHMWPE bar using a Ziegler type catalyst efficiency low pressure synthesis, molecular weight control 150-300 million or more according to need. Taking into account the thermal degradation of the molecular processes, thus having a viscosity-average molecular weight greater than 1.7 million high-density polyethylene is processed into various products, in order to be able to be more advantageous.
