High Silica Cloth Plain Weave | Silica Content >98%
High-Temperature Resistant High Silica Fabric for Fire & Thermal Protection
High Silica Cloth Plain Weave (>98% SiO₂) is a premium high-temperature textile engineered for extreme heat resistance, thermal insulation, and fire protection applications.
Manufactured from continuous high-silica fibers and woven in a balanced plain weave construction, this fabric delivers exceptional thermal stability, low thermal conductivity, and excellent chemical resistance in harsh industrial environments.
Designed for continuous exposure to temperatures up to 1000°C and short-term exposure up to 1200°C, high silica cloth is widely used in aerospace, foundries, power plants, welding protection, and fire safety systems.
Key Technical Advantages
- Silica Content: >98% (High-Purity SiO₂)
- Maximum Continuous Temperature: 1000°C
- Short-Term Temperature Resistance: Up to 1200°C
- Low Thermal Conductivity
- Excellent Flame & Spark Resistance
- Non-Combustible & Non-Asbestos
- Excellent Chemical & Oxidation Resistance
The plain weave structure ensures uniform thickness, high tensile stability, and easy fabrication into insulation blankets, curtains, and protective covers.
Fabric Construction & Engineering
High Silica Cloth is produced by converting E-glass fabric through a specialized leaching process to remove impurities, resulting in ultra-high silica content. The plain weave pattern provides:
- Balanced strength in warp and weft directions
- Dimensional stability at elevated temperatures
- Smooth surface finish for coatings and laminations
- Reduced fraying during cutting and fabrication
This construction makes the fabric ideal for both flexible insulation and reinforced fire-resistant systems.
