聚四氟乙烯是一种重要的工程塑料.它既能耐二、三百度的高温,又能耐低温,在接近绝对零度时仍有韧性.它在酸、碱、有机溶剂、强氧化剂及几乎一切化学试剂中都不起变化,不沾水、不沾油,又有优良
Polytetrafluoroethylene is an important engineering plastic.It can resist two or three hundred degrees of high temperature, but also low temperature, at near absolute zero still toughness.It is in acid, alkali, organic solvents, strong oxidants and almost all chemical Reagents can not afford to change, do not stick to water, not oil, there are excellent
