PTFE envelope gasket with core material of flexible materials (Asbestos; non-asbestos; rubber, etc.), which is wrapped by PTFE.

PTFE enveloped gasket is a kind of non-metal gasket. Normally it is made up by cladding part and packing. The clart, the material adding part, which is normally made of teflon function as anti-corrosion and the packing is non-metal sealing material which has good elasticity and can be with or without metal enhancing layer. These sealing gaskets are divided into style v, style u, style l according to the different in frame of inner core. In the field like petroleum, chemical industry, medicine industry,and food industry, we use teflon gasket to make sure the cleanness. and it also used in sealing of strong acid, strong alkali strong oxidizer, chlorine, and other material don't allow pollution.
