聚四氟乙烯棒材 |
|
|
PTFE Rod
【 特 征 Festures】
|
|
聚四氟乙烯棒有二种。直径4-9mm的棒选用分散聚合聚四氟乙烯树脂经糊膏挤压加工制成；直径10-50mm的棒选用悬浮聚四氟乙烯树脂径柱塞挤压加工制成；直径50mm以上的棒径模压加工制成。
在已知塑料中聚四氟乙烯具有最优良的耐化学腐蚀性能与介电性能，不老化、不粘、在无负荷情况下能在-180%°C - +260°C温度下使用，在已知固体材料中它具有最低摩擦系数。
There are two kinds of PTFE rods to offer . One is manufactured by paste extruding method in the diameter from 4 to 9mm and the other is made by ramertruding methruding method in the diameter from 10 to 150mm；Rods over diameter 150mm are manufactured by moulding.
PTFE is the most chemical-resistant plastic of all known plastics . It does not age.
PTFE has a wide range of practicalble temperature from -180℃～+250℃ and a wax-like surface to which anything hardly sticks.
PTFE has the lowest coefficient of friction of all know solid materials . It has the best electrical properties of all plastics.
