PFA塑料原料用途是什么?①。適用于制造耐腐蝕零件,減少磨損的零件,密封件,絕緣零件和醫療設備零件。②。高溫電線,電纜絕緣,防腐設備,密封材料,泵閥襯套和化學容器。2.成型性能①。晶體材料,吸濕率低。可以通過熱塑性塑料中常用的加工方法將其加工成制品。②。流動性差,易于分解,分解時會產生腐蝕性氣體。成型溫度應嚴格控制在不超過475度,模具應加熱到150-200度,澆口系統對物料流動的阻力應低。③。半透明顆粒,注塑和擠出成型。成型溫度為350-400℃。高于475℃時,容易引起變色或氣泡。請注意,脫模可能很困難。④。由于熔融材料對金屬具有腐蝕作用,因此模具需要長期進行鍍鉻處理。 。以上文獻若需轉載請備注出處:pbt塑料 //shanglikaiguan.cn/
