Expanded polytetrafluoroethylene sheet is a high-sealing backing plate made of polytetrafluoroethylene, and does not contain any adhesives and additives. It has strong resistance to chemical corrosion; the special design makes the backing plate has strong resistance to creep and cold flow, so as to ensure the stable maintenance of the bolt tightening force during the sealing process; it has good flexibility, compression resilience and resistance High and low temperature, non-aging, self-lubricating, etc.; soft and easy to cut, can be machined or hand-cut, easy to install; has a unique conformable molding ability, no need to increase the pressing force, greatly extending the life of the flange. Make up for irregularities in the sealing surface, reliable sealing performance, especially excellent gas sealing performance.
