PTFE gasket has strong corrosion resistance and friction-resistance,By adding filler such as glass fiber,carbon fiber,copper powder,graphite,asbestos,MOS2,AL2O3,carbon powder,ceramic fiber,metal powder,polyamide,PS,the hardness,compression strength and abrasion resistance of the products is improved ,in addition,it will have good heat conductivity and low heat expansion coefficient.
Main Features
1.PTFE gasket is manufactured by molding method with suspended PTFE resin.
2.PTFE compared with other plastics, has superior properties against chemicals and temperature
3. Excellent properties, PTFE has a wide application as a sealing material.
4.it will take 5-8days to finished the sample .at that time we will show the sample picture to you first .
5.Now molds can be made according to customers requirements
