PTFE Sigma

Sigma 500

is a fully restructured sintered PTFE based sheet sealing material ensuring maximum resistance to creep under the high compressive loads generated in bolted flanged connections. Compression is enhanced through the inclusion of silica microspheres.
Sigma 500 finds use in a wide variety of sealing applications. Its is particularly suited to sealing against a wide variety of aggressive chemical media such as strong oxidising and reducing agents, acids and alkalis.
