Thermiculite 835 Spiral Wound

Exclusive to Flexitallic, this revolutionary material comprised of chemically and thermally exfoliated vermiculite makes it an excellent filler material for use in spiral wound gaskets.

Product Features

This naturally occurring mineral, with a plate-like structure, simulates that of exfoliated graphite, with one notable exception – it is not susceptible to oxidation and therefore maintains seal integrity through a wide range of extreme temperatures. It exhibits exceptional chemical resistance.
Capable of sealing temperatures up to 1800°F (982°C), Thermiculite® 835 is an ideal material selection for critical and problematic applications. It is versatile, fire safe and its excellent sealing characteristics are superior to other high temperature materials such as mica and ceramic. Thermiculite® 835 is especially suitable for high temperature applications where there is a concern about oxidation of flexible graphite filler.
