Thermiculite

A breakthrough in both heat and chemical resistance, Thermiculite Critical Service materials are rated for temperatures up to 1800ºF and have passed the API 607 fire test.

Available in spiral wound and Flexpro™ (Kammprofile) facing styles, they provide safer, more cost-effective alternatives to industrial sealing problems where ultra-high heat resistance is critical; ex: oxidation of graphite in nuclear power exhaust systems.

They are suitable for replacing aramid, glass, and carbon fiber; PTFE; and graphite gaskets in a number of industrial applications.
