Applications of High Silica Fabric
High silica fabric is suitable for industrial applications requiring flexible, heat-resistant textile materials.
1. Welding Blankets and Spark Protection
High silica woven fabric can be used to manufacture welding blankets, welding curtains, and spark-resistant protective covers. It helps shield surrounding equipment and work areas from welding sparks and hot particles.
2. Industrial Furnace Insulation
In industrial furnaces and high-temperature processing equipment, high silica textile can serve as a flexible thermal barrier or an outer layer in selected insulation assemblies.
For additional insulation materials, explore our Ceramic Fiber Blanket range.
3. Removable Insulation Jackets
High silica fabric can be fabricated into flexible covers for pipes, valves, flanges, and industrial equipment. The finished insulation system must be designed according to operating temperature, insulation thickness, and mechanical requirements.
4. Fire Curtains and Thermal Barriers
When the fabric grade and construction meet the required performance criteria, high silica fabric can be used in selected fire protection systems, thermal barriers, and protective textile assemblies.
5. Industrial Heat-Resistant Components
Other applications include expansion joint fabrics, protective covers, and selected composite reinforcement systems, depending on the fabric construction and service conditions.
High Silica Fabric vs. Conventional Fiberglass Fabric
High silica fabric and conventional fiberglass fabric differ primarily in silica content and temperature performance.
