PTFE Expand Tape , PTFE Expand Stripe,PTFE Expand Tape Food Grade
Description:
Made from import Dakin PTFE material, the expanded PTFE joint sealant tape with self-adhesivehas have very good flexibility, compression resilience, creep resistance, high/low temperature resistance, excellent corrosion resistance, non-aging property and self-lubricity.
Application Range:
For sealing various enameled linings, glass linings, plastic linings, rubber linings, graphite linings, and the flange faces of stainless/titanium steel towers, heat exchangers, reactors, etc.;
For sealing the flange faces of various pipelines and pipe fittings;
For sealing the flange faces of large-diameter equipment with bad surface machining accuracy, large uneven area, irregular shape and bolt fastening force difficult to be enough or unsuitable to be too big;
For sealing strongly corrosive media and fluid protected against any pollution.
