PTFE/Teflon Gasket is made by cutting Teflon stick, pipe and sheet into flat shape Teflon Gasket(PTFE gasket), v shape Teflon Gasket or valve annulus Teflon Gasket.Graphite Teflon Gasket was reinforced by glass fibre.The compounding of glass fibre strengthen the stability of PTFE.PTFE Gasket can bear the most bitter chemical medium, and PTFE gasket has good anti-creeping performance.PTFE gasket is a replacement of asbestos. PTFE gasket is anti-creeping, anti-cold-flow, anti-low-temerature. PTFE gasket has no pollution. Graphite Teflon Gasket can also be reinforced with glass fibre and othe material.We have PTFE gasket reinforced with glass fibre,graphite PTFE gasket,reformative PTFE gasket,PTFE envelope gasket,ect.
PTFE envelope gasket are use for type of static seal. PTFE envelope gasket is composed of elastic materials. such as PTFE envelope gasket composed of compressed non-asbestos sheet and a PTFE envelope cove,PTFE envelope gasket composed of rubber and a PTFE envelope cove,PTFE envelope gasket composed of Ceramics and a PTFE envelope cove,etc.PTFE envelope gasket has superior properties against chemical (not affected by all chemicals except molten alkali metal and fluorine at elevated temperature).PTFE envelope gasket has a wide working temperature range. (180-260℃).PTFE envelope gasket has low coefficient of static and dynamic friction. PTFE envelope gasket is the best of the “non-stick” materials.

PTFE has superior properties against chemical (not affected by all chemicals except molten alkali metal and fluorine at elevated temperature) and a wide working temperature range. (from –180~260℃) the coefficient of static and dynamic friction of PTFE are very low. PTFE is the best of the “non-stick” materials. It has excellent weathering and aging characteristics.
Application:PTFE envelope gasket is used to seal pipe flanges glass lined, PVC or FRP. Low bolt torque effecting a seal and chemical compatibility is a main characteristic of this type of gasket. |
