SILTEX® Woven Silica Fabric

siltex 18

Made with continuous filament, 96% amorphous silica fibers, SILTEX® Woven Silica Fabric is a chemical resistant material that also has high temperature and abrasion resistance.

Available in a variety of weights ranging from 18 oz/sy to 70 oz/sy, SILTEX® Woven Silica Fabrics are widely used as welding blankets and welding curtains for the safety of personnel and equipment. Our 18-ounce silica fabric and our 36-ounce silica fabric are ideal for use in hot works operations.

In addition to use for welding safety, SILTEX® Woven Silica Fabrics are also used as thermal barriers to reduce energy costs, and can be coated with silicone for use in applications that require higher abrasion resistance.
