Properties of Sigraflex ®

Sigraflex ® HD graphite sheet is very good pressure resistant and has a high temperature resistance. The material is also non-sticking. These properties, along with the good chemical resistance, make the material perfectly suitable for application in steam systems in amongst others the process industry and the (petro)chemical industry.

Sigraflex ® Email is specially developed for use in PTFE envelope gaskets. A PTFE envelope gasket is a composed gasket. It often consists of an envelope of PTFE with two inlays of graphite (Email), with a corrugated 316SS ring in between. The envelope gasket is mainly applied as a flange seal in applications where a high chemical resistance and high pressure resistance is required.
