PPS的概念:
的中文名称是聚苯硫醚,是一种新型高性能热塑性树脂,具有机械强度高、耐高温、耐化学药品性、阻燃、热稳定性好、电性能优良等优点。在电子、汽车、机械及化工领域均有广泛应用。PPS有交联型(深褐色)和线型(白色)两种,东丽同时生产这两种PPS。
PPS的突出性能有:
1. 良好的耐热性能,热变形温度一般大于260度,可在180~220℃温度范围使用,PPS是工程塑料中耐热性*的品种之一。
2. 耐腐蚀性接近四氟乙烯,抗化学性仅次于聚四氟乙烯

Lub tswv yim ntawm PPS:
Lub npe Suav yog polyphenylene sulfide, uas yog qhov ua tau zoo tshiab thermoplastic cob nrog qhov zoo xws li kev siv tshuab muaj zog, siab kub tsis kam, tshuaj lom neeg tsis kam, nplaim taws rov qab, zoo thermal stability, thiab cov khoom siv hluav taws xob zoo heev. Nws yog dav siv hauv cov khoom siv hluav taws xob, tsheb, tshuab, thiab tshuaj lom neeg engineering. Muaj ob hom PPS: sib txuas sib txuas (tsaus xim av) thiab kab (dawb), thiab Dongli tsim ob hom PPS ib txhij.
