Silica Woven Fabric and Textiles

siltex 18

SILTEX® Woven Silica Fabric and Textiles are high-temperature resistant materials with a continuous operating temperature of 1800° F • 982°C.

Widely used for equipment and personnel protection in industries such as Welding, Shipbuilding, Metals Processing, Refineries, Foundries, Power Generation, and Petrochemical, SILTEX® Woven Fabrics and Textiles can be applied to applications where thermal insulation is essential to the reduction of maintenance and energy costs.

Comprised of high purity, high strength 96% amorphous silica fibers, SILTEX® Woven Fabrics and Textiles are optimal in applications where E-glass fabrics would typically fail.
