TESLON Expanded PTFE Sheet


TESLON Expanded PTFE Sheet consists of 100% Virgin PTFE. The manufacturing process produces a multidirectional fibrous texture which gives the material its special properties. This creates a soft and pliable, yet very tough gasket that has excellent resistance of pressing, creep relaxation and cold flow. It can seal the uneven and damaged flanges. TESLON sheet is a soft highly compressible sealing material and shows very low compression rates & exhibits very little increase in width even under extreme sealing conditions. The exceptional malleability of TESLON Expanded PTFE can compensate for damaged sealing surfaces. This allows use with stress sensitive connections and applications where only a limited flange load is available e.g. Plastic Flanges, Glass Flanges, etc.
