Flexible, High-Silica Fabric for Welding Protection and Extreme Temperatures up to 2300F

Woven from yarn that is composed of more than 96% silica, Z-Sil™ Silica Fabrics provide superior protection from high temperatures, sparks, and slag. Z-Sil Silica Fabrics are treated with an inorganic high temperature coating that improves abrasion resistance and remains with the fabric even at high temperatures.

We offer Silica Fabrics in 2 weights: 18 ounces per square yard for applications where flexibility is important or 36 ounces per square yard for applications where superior insulation is necessary. Both styles can be laminated with Z-Flex Multilayer Aluminization for radiant heat protection.

Z-Sil™ Silica Fabric supports continuous operating temperatures up to 1800°F (980°C) and peak temperatures to 2300°F (1260°C).

Because of its superior temperature resistance, silica fabric is ideal for protecting people and equipment during metal cutting, stainless steel welding, and heavy welding operations. 

Common Applications
