UHMWPE板加工耐磨块的性能取决于它的聚合方式。在中等压力(15-30大气压)，有机化合物催化条件下进行Ziegler-Natta聚合而成的是高密度聚乙烯(hdpe)。这种条件下聚合的聚乙烯分子是线性的，且分子链很长，分子量高达几十万。如果是在高压力(100-300MPa)，高温(190-210°C)，过氧化物催化条件下自由基聚合，生产出的则是低密度聚乙烯(LDPE)，它是支化结构的。

The performance of UHMWPE plate to process wear-resistant block depends on its polymerization mode. High density polyethylene (HDPE) was synthesized by Ziegler Natta polymerization under medium pressure (15-30 atmospheric pressure) and catalysis of organic compounds. The polyethylene molecule polymerized in this condition is linear, and the molecular chain is very long, and the molecular weight is up to several hundred thousand. If it is polymerized under high pressure (100-300mpa), high temperature (190-210 ° C) and peroxide catalysis, LDPE is produced, which is branched structure.
