PTFE Coated Graphite Gasket PTG-90 聚四氟乙烯/石墨复合垫片PTG-90

Stick PTFE film on both sides of expanded graphite sheet or reinforced graphite gaskets. Cut it into different size as customer's request. It has excellent corrosion resistance and compression resilient.  Even under very low Pre-tightening torque, it still have excellent sealability. Specially for hot press oil, LNG, LN2, and strong acid and alkali, etc. media.

在纯石墨板或者增强石墨板的两面贴聚四氟乙烯薄膜，根据客户需要加工成所需尺寸。 兼具四氟的耐腐蚀性和膨胀石墨的高压缩回弹率等密封性能，在预紧力很低却高压的工况下发挥出良好的密封性能。用于热媒体油等渗透性强介质，液化天然气，液化氮等超低温介质和强腐蚀性介质的管道法兰，液压计，阀盖等的密封。
