High Silica Cloth Twill Weave | Silica Content >98%
Flexible High-Temperature Silica Fabric for Advanced Fire & Thermal Protection
High Silica Cloth Twill Weave (>98% SiO₂) is a premium high-temperature textile engineered for applications requiring superior drapeability, enhanced abrasion resistance, and extreme heat performance.
Manufactured from high-purity continuous silica fibers and woven in a twill weave construction, this fabric combines excellent thermal stability with improved flexibility compared to plain weave silica fabrics.
Designed for continuous operating temperatures up to 1000°C and short-term exposure up to 1200°C, twill weave high silica cloth is ideal for fire curtains, welding blankets, removable insulation covers, and complex-shaped thermal protection systems.
Key Performance Advantages
- Silica Content: >98% (High-Purity SiO₂)
- Continuous Temperature Resistance: Up to 1000°C
- Short-Term Heat Exposure: Up to 1200°C
- Superior Flexibility & Drapability
- Improved Abrasion Resistance
- Non-Combustible & Non-Asbestos
- Excellent Resistance to Flame, Sparks & Molten Metal Splash
The twill weave pattern provides a smoother surface and better conformability around curves, joints, and irregular equipment.
Fabric Construction & Engineering Benefits
High silica cloth is produced through a controlled leaching process that removes non-silica components from glass fibers, achieving ultra-high silica purity. The twill weave structure offers distinct advantages:
- Enhanced fabric flexibility compared to plain weave
- Higher resistance to surface wear and mechanical damage
- Reduced yarn crimp for smoother handling
- Better performance in movable or foldable insulation systems
These properties make twill weave silica cloth particularly suitable for dynamic or reusable fire protection applications.
