PTFE elastic belt is a good sealing material, it is by pure PTFE dispersion resin, made by layering high-temperature tensile. It has a low coefficient of friction, resistance, chemical corrosion, good sealing, non-hydrolyzed, non-hardening, etc., it can be -250 +280 temperature used, 100% Expanded PTFE tape to ribbon form for the goods, on the back of self-adhesive, easy to install, the product is a large number of stocks, does not produce cutting losses, resistance to compression is good, right irregular flange surfaces and require high accuracy of the place has strong adaptability. For reactor, turbine generators and a variety of special-shaped mouth cans, barrels sealed.
