Pure PTFE Gasket，Polytetrafluoroethylene Gasket

Item No.:ZD-G1600

Description: ZD-G1600 is made by cutting PTFE stick, pipe and sheet into flat shape PTFE gasket, v shape PTFE gasket or valve annulus PTFE gasket.PTFE gasket has 100% PTFE structure.It can bear the most bitter chemical medium, and PTFE gasket has good anti-creeping performance.PTFE gasket is a replacement of asbestos,and it is anti-creeping, anti-cold-flow, anti-low-temerature.PTFE gasket has no pollution and is easy to install and replace. under small pre-stress force,it can bear great internal pressure even in a environment of changing pressure. It is the best suit the condition with rough and fragile flange and alternately-changing temperature.

Modified PTFE Gasket

Item No.:ZD-G1610

Description:As we know,PTFE gasket is anti-creeping, anti-cold-flow, anti-low-temerature and PTFE gasket has no pollution. If we add some more useful element into the PTFE,the compression resistance and high temperature resistance will be more perfect.For example,can add some fibreglass,graphite,bronze to improve the character of pure PTFE gasket.We have PTFE gasket reinforced with glass fibre,graphite PTFE gasket,reformative PTFE gasket,PTFE bronze gasket,ect.

PTFE Graphite-filled Gasket:PTFE(teflon) graphite-filled is synthetic material made of PTFE and grapphite.It has perfect compressibility,recovery and sealing capability.Compared with traditional PTFE,it improve the low-flow and creep properties.It is more durable than normal PTFE gasket and extend the maintenance period of flange.So PTFE(teflon) graphite is economical choice.

PTFE Glass-filled Gasket:It is stamps gaskets from virgin and glass-filled PTFE.PTFE glass-filled gasket resist virtually all acids and caustics;It has the lowest known coefficient of friction of any solid, and has excellent electrical insulating properties. It has a continuous service temperature range of minus 350F to 500F. It is the ideal material for use in the petrochemical and chemical processing industries, and because it is FDA compliant, it can be used in the food processing and pharmaceutical industries also.

It have a shrinkage rate of approximately 5%. Glass filled PTFE gaskets have a lower shrink rate, because the glass fiber filler makes them harder, so they require less compression to seal adequately.
