Description and Applications

In addition to the filler/facing materials offered in the metallic gasket product section,TEADIT® offers the following high temperature materials.

SGL® SIGRAFLEX Type APX2 Flexible Graphite

Flexible Graphite with advanced oxidation inhibition & excellent sealability

MICA

Phlogopite Hi-Temp grade to 1832°F (1000°C). Used in some hot gas applications, and as filler/facing for spiral wound & camprofile gaskets and as an oxidation barrier in combination with other sealing materials.

Ceramic Fiber

Used in some hot gases/ low pressure service. This material is also used as filler for metallic gaskets or in combination with other sealing materials. Temperature limit: 2000°F (1090°C).

XHR

Extreme heat resistance. Uses combination of mica barriers and APX2 to provide exceptional sealing ability to 1500°F (815°C).

PTFE

Polytetrafluoroethylene provides superior chemical resistance and great sealing ability. Typically rated to approximately 500°F (260°C).

Flexible Graphite

Provides soft conforming material in fire-safe design with excellent chemical resistance. Typically rated to 842°F (450°C).
