背景技术
聚苯硫醚英文简写为PPS，是分子主链中带有苯硫基的热塑性树脂，聚苯硫醚是一种结晶性的聚合物。PPS是一种综合性能优异的特种工程塑料，具有优良的耐高温、耐腐蚀、耐辐射、阻燃、均衡的物理机械性能和极好的尺寸稳定性以及优良的电性能等特点，被广泛用作结构性高分子材料，通过填充、改性后广泛用作特种工程塑料。同时，还可制成各种功能性的薄膜、涂层和复合材料，在电子电器、航空航天、汽车运输等领域获得成功应用。自聚苯硫醚实现产业化以来，已经开发了PPS涂料、PPS工程塑料、PPS纤维及其集尘滤袋等众多的品种，并在相关领域得到了广泛应用，取得了良好的经济效益、社会效益和环境效益。
PPS薄膜可分为流延膜和双拉膜，其用途是有差别的，国内目前均不能生产。流延膜主要用于制造先进复合材料，现有用户为航空器、船舶制造部门，价格便宜后可以用于车辆、机械制造领域，由于PPS薄膜的制造需要高品质的PPS树脂，国内未能实现该薄膜制造的重要原因之一就是PPS树脂不能完全达到制造薄膜的要求。
