VEXTRA® (FLVB) TP Black Cloth

VEXTRA® (FLVB) is an aramid and fiberglass blend heat resistant cloth with a vermiculite armor-like coating that is inorganic, chemically inert, noncombustible and odorless. The vermiculite coating enhances the fabric rating to 1000°F (540°C). All of AMI’s VEXTRA® coated fabrics, enable them to remain stable at up to 50% higher temperatures than the uncoated counterparts. VEXTRA fabrics are tough enough to withstand very hostile work environments.

VEXTRA® Textiles are 100% fiberglass coated with a golden vermiculite solution made of plate-like mineral crystals. This non-combustible coating acts like armor when heat strikes the fabric, causing the heat to travel across the fabric rather than through it, shielding the fiberglass from the heat source.
