特征
聚四氟乙烯板材采用悬浮聚合聚四氟乙烯树脂模塑加工制成。在已知塑料中它具有最好的耐化学腐蚀性能，不老化，在已知固体材料中它具有最佳的摩擦系数，在无负荷情况下能在-180℃~+260℃使用。
Features:
PTFE molded sheet is manufactured by molding method with PTFE granular resin.
PTFE is the most chemical resistance of all known plastics.lt does not age.lt has the lowest coefficient of friction of all known solid materials and a wide range of practicaboe temperature from-180℃~+260℃。 |
