Properties of Sigraflex ® graphite


Sigraflex ® HD 

This 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.

This material 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.
