A breakthrough in thermal and chemical resistance, Thermiculite® High Temp materials for gaskets are rated for temperatures up to 1000ºC and have passed the fire test API 607.

Thanks to a unique recipe, we can offer Thermiculite® as a sheet material, as a filler for spiral-wound gaskets, as a filler for camprofiles, as well as in many other production lines.

Thermiculite® sealed materials withstand high temperatures in critical conditions, corrosive environments and are free of oxidation. Thermiculite® is suitable for the replacement of aramid, glass and carbon fibers, PTFE and graphite gaskets in a number of industrial applications.

Since its inception, Thermiculite gasket material has proven itself as an effective long-term sealing solution in over 500 of the most demanding industrial sealing applications—the most complete range since asbestos.
