高分子聚乙烯衬板

产品介绍

     本公司常年专业生产高分子聚乙烯衬板、煤仓衬板、高分子耐磨板以及高分子聚乙烯板等产品。而高分子聚乙烯衬板时本公司专业生产的最佳产品。高分子聚乙烯衬板具有的分子链长度是高密度聚乙烯的10~20倍。更长分子链(更高的分子量)赋予UHMWPE的主要优势在于韧性、耐磨性和抗应力开裂性。由于它是聚乙烯的一种,UHMWPE也具有润滑性、耐化学性和通用HDPE的优良电性能。 长分子链使材料在通用的模塑和挤塑设备上难于加工。加热到熔点以上,UHMW变成透明的,但不流动。 化学和性能 UHMWPE是用齐格勒聚合法生产的。加工过程要求特别高的纯净度,乙烯单体杂质控制在百万分之几。产品是一种白色粉末,颗粒大小与食盐相近。该聚合物通过溶液粘度的方法来检测,据此计算特性粘度 (IV)和分子量(MW)。UHMWPE按ASTM定义其重均分子量(MW)大于300万。 现有的UHMWPE品级的 MW在300~ 600万之间。一般按照 IV分类, IV为 20dl./g约等于 MW为 300万。 IV为30表示MW为600万。一些品级含添加剂,为特殊最终应用。
