Material Composition and Application

This form of joint sealant is specially processed by expanding 100% pure polytetrafluoroethylene (PTFE). It provides a soft, highly compressible gasket for longer life and trouble-free sealing. Its form-in-place versatility also cuts maintenance and storage costs. The high compressibility of ePTFE Joint Sealant enables it to effectively fill flange imperfections for a tight, leak-free seal. Under pressure, it provides a very wide, thin ribbon-like joint sealant. Unlike conventional PTFE which is prone to cold flow, ePTFE Joint Sealant has good creep resistance and bolt torque retention properties. It does not support bacterial growth or cause product contamination and is FDA compliant. It has virtually no shelf-life concerns since PTFE is unaffected by normal environmental conditions. ePTFE Joint Sealant has excellent resistance properties to chemical attack with a pH range of 0-14.

It is ideal for most chemical services at temperatures to 600°F (316°C) and pressure to 3,000 psi (207 bar). It is also suitable for cryogenic use to -321°F (-196°C). The sealant is available in roll form which helps reduce storage space and is available in a wide variety of thicknesses and lengths.
