Specification of Teadit GR 1700 Graphite HOCHDRUCK
Teadit GR 1700 Graphite HOCHDRUCK
APX2 HOCHDRUCK Graphite Sheet with Multiple Foil Inserts TEADIT SIGRAFLEX APX2 Hochdruck-GR1700 is a multilayer, high strength gasket sealing sheet designed for high-temperature applica tions. The sheet is comprised of 0.020 "thick layers of highly resistant hydrocarbon SIGRAFLEX APX2 exible graphite and 0.002" thick inserts of 316 l stainless steel foil, manufactured with SIGRAFLEX Hochdruck technology. Teadit GR 1700 APX2 properties Hochdruck is speci cally designed for high temperature at gasket applications. It combines the outstanding weight loss characteristics of SIGRAFLEX APX2 exible graphite and reinforcing layers of metal in SIGRAFLEX Hochdruck technology.

It is also suitable for use in the manufacture of gaskets for sight glass, pumps, valves, and ttings etc. Gaskets made from this type of sheet perform well in critical applications due to the high mechanical strength and blow-out resistance, working pressure resistance up to 3600 psi (250 bar), excellent chemical resistance, very low cold or hot relaxation, and a maximum permissible gasket stress. Among its advantages, there is good conformation to sEaling surfaces, excellent torque retention and high sealability.
