Vermiculite Coated Fiberglass:
FlameShield 1500 - Very High Temperature, Heat & Flame Resistant Tadpole Gasket
This high temperature, heat and flame resistant vermiculite coated fiberglass fabric will withstand temperatures of 1500°F / 815°C continuous exposure.  The base High Temperature fiberglass fabric is fabricated from high quality type E fiberglass that will not burn.  The fabric is then coated with a vermiculite dispersant.

This material resists most acids and alkalis and is unaffected by most bleaches and solvents.  It is highly flexible and conformable.

The bulb material can be Fiberglass Rope, Stainless Steel Mesh or Inconel Mesh.

Tested and certified to meet ASTM E 162, ASTM E 662 and SMP 800C for surface flammability, smoke and toxic gas generation.
