常用塑料的性能用途

作者:奥凯高分子  发布时间:2017-07-28 15:28  点击量:
  PE是聚乙烯塑料,化学性能稳定,通常制作食品袋及各种容器,耐酸、耐碱及盐类水溶液的侵蚀,但不宜用强碱性洗涤剂擦拭或浸泡。
 
  PP是聚丙烯塑料,无毒、无味,可在100℃的沸水中浸泡不变形、不损伤,常见的酸、碱有机溶剂对它几乎不起作用。多用于食具。
 
  PS是聚苯乙烯塑料,容易着色、透明性好,多用于制作灯罩、牙刷柄、玩具、电器零部件。它耐酸碱腐蚀,但易溶于氯仿、二氯乙烯、香蕉水等有机溶剂。
 
  PVC是聚氯乙烯塑料,色泽鲜艳、耐腐蚀、牢固耐用,由于在制造过程中增加了增塑剂、抗老化剂等一些有毒辅助材料,故其雷电竞app下载一般不存放食品和药品。
 
  ABS是由丙烯腈、丁二烯、苯乙烯聚合的塑料,它色彩醒目,耐热、坚固、外表面可镀铬、镍等金属薄膜,可制作琴键、按钮、刀架、电视机外壳、伞柄等。
 
  PA是尼龙塑料,它的特性坚韧、牢固、耐磨,常用于制作梳子、牙刷、衣钩、扇骨、网袋绳、水果外包装袋等。无毒性,但不可长期与酸碱接触。
