PTFE, Hostaflon TF, Teflon PTFE, Polytetrafluoroethylene聚四氟乙烯, White白色
★氟化物中最經濟及廣受歡迎★
PTFE resin is in a class of paraffinic polymers that have some or all of the hydrogen replaced by fluoride. PTFE has exceptional resistance to chemicals. PTFE has useful mechanical properties from cryogenic temperatures at 500° F (280° C) continuous service temperatures. Its coefficient of friction is lower than almost any other material. It also has a high oxygen level.
聚四氟乙烯俗稱鐵氟龍，它擁有化學抵抗的優異特性，而且連續使用溫度範圍非常廣，無論是在低溫或是高溫(+260至-240℃)，摩擦係數也幾乎都比其他塑膠材料低，滑動性能極佳(使用四氟乙烯沒有蠕動效應)，使用在高頻範圍也有良好的絕緣性

產品特性
★幾乎可耐所有化學藥品的侵蝕
★PTFE的機械性能可藉由碳、玻璃纖維、銅粉、石墨、二硫化鉬的填充，改善其耐磨性和機械強度
★跟其他氟化物比起來，由於PTFE線膨脹係數較大，尺寸穩定性較差，冷流性(蠕變)較大，耐磨差，極限PV值低，抗輻射和電暈性也較差，使用上須注意，建議可參考其他氟化物之特性，以用於不同的環境條件
