F4棒

聚四氟乙烯棒有二种。直径4～9mm 的棒选用分散聚四氟乙烯树脂经糊膏挤压加工制成；直径4～200 mm的棒选用悬浮,聚四氟乙烯树脂经柱塞挤压加工制成；直径200mm以上的棒经模压加工制成。

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℃~+260℃温度下使用，在已知固体材料中它具有最低摩擦系数。

Areas of application

Shipbuilding

In order to achieve lightweighting of automobiles, effectively reduce costs and fuel consumption rates, major automobile companies generally adopt optimization design methods to design cars, making the materials used for large car coverings thinner and thinner. To solve the problems of insufficient local strength and stiffness caused by this, various reinforcement materials have been developed and widely used in various types of automobiles.
