Vermiculite Fiberglass Exhaust Wrap compared to uncoated fiberglass exhaust wrap, vermiculite coated fiberglass provides increased resistance to high temperature, flame, and abrasion. In addition, the vermiculite film helps to seal against gases and liquids. This exhaust wrap is completely non-flammable.
Vermiculite Fiberglass Exhaust Wrap is a high temperature, heat and flame resistant thermal insulating tape that will withstand temperatures of 1500°F / 815°C continuous exposure. The base High Temperature fiberglass exhaust wrap is fabricated from high quality type E fiberglass that will not burn.  The wrap 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 confortable.
Applications for this product include thermal insulation and/or protection of wires, cables, hoses, pipe and tube, as well as affording energy savings and personnel protection.
The vermiculite coating also adds abrasion resistance to the wrap.
