PTFE expansion board ：

from teflon The expanded high sealing backing plate does not contain any adhesive and additive. Extremely strong chemical corrosion resistance; The special design enables the backing plate to have a strong creep resistance and cold flow performance, thus ensuring the stability of the bolt tightening force during the sealing process; It has good flexibility, compression resilience, high and low temperature resistance, aging resistance, self lubrication, etc; Soft and easy to cut, which can be cut mechanically or manually for easy installation; It has unique compliance forming ability, and does not need to increase the compression force, greatly extending the service life of the flange. Make up for the irregular sealing surface, and the sealing performance is reliable, especially the gas sealing performance is excellent.
