Woven silica fabric is a high-temperature textile made from >96% pure SiO₂ (silicon dioxide) fibers. Designed to withstand continuous exposure to extreme heat, this advanced material is ideal for demanding thermal protection, insulation, and fire barrier applications. With outstanding resistance to high temperatures, chemical corrosion, and mechanical stress, woven silica fabric is trusted across aerospace, metallurgy, automotive, power generation, and industrial sectors.

We offer a full range of woven silica fabrics, including specialty surface treatments to meet specific environmental and mechanical challenges:

1. Uncoated Woven Silica Fabric

This is the base material, woven from amorphous silica fibers. It can withstand continuous temperatures up to 1000°C (1832°F) and short-term exposures up to 1650°C (3002°F). It is non-combustible, non-toxic, and offers low thermal conductivity. Common uses include:

• High-temperature insulation blankets

• Welding and fire curtains

• Expansion joint covers

• Protective wraps for pipes, hoses, and cables

2. Silicone Coated Silica Fabric

Coated with high-grade silicone rubber, this variant provides added flexibility, water resistance, and abrasion protection. It maintains thermal resistance while offering a smooth surface finish for easier handling and sealing. Ideal for:

• Removable insulation jackets

• Fire blankets with better handling

• Welding protection with oil and moisture exposure

• Flexible thermal wraps

3. Aluminized Silica Fabric

This fabric features an aluminized coating that reflects up to 95% of radiant heat, while maintaining the base silica fabric’s high-temperature integrity. It is perfect for environments where radiant heat is a primary concern. Key applications include:

• Heat shields for automotive and aerospace

• Radiant heat barriers in industrial furnaces

• Fire protection curtains near molten metal processes

4. Vermiculite Coated Silica Fabric

Vermiculite is a natural mineral that enhances abrasion resistance and prevents fraying, while still maintaining high heat resistance. It is a cost-effective solution for heavy-duty insulation and flame protection. Common uses include:

• Welding blankets and pads

• Fire curtains in heavy industry

• Thermal insulation in furnaces and kilns
