High Silica Cloth 4H Satin Weave | Silica Content >98%
Ultra-Smooth High-Temperature Silica Fabric for Advanced Thermal & Fire Protection
High Silica Cloth 4H Satin Weave (>98% SiO₂) is a high-performance thermal textile engineered for applications demanding maximum flexibility, superior surface smoothness, and extreme heat resistance.
Manufactured from high-purity continuous silica fibers and woven in a 4-Harness (4H) Satin weave, this fabric offers lower yarn crimp, improved drapeability, and enhanced mechanical stability compared to plain and twill weave silica fabrics.
With continuous temperature resistance up to 1000°C and short-term exposure up to 1200°C, 4H satin weave high silica cloth is widely used in aerospace insulation, fire curtains, thermal shielding, composite tooling, and high-end fire protection systems.
Key Performance Advantages
- Silica Content: >98% (Ultra-High Purity SiO₂)
- Continuous Operating Temperature: Up to 1000°C
- Short-Term Temperature Resistance: Up to 1200°C
- Exceptional Flexibility & Drapability
- Very Smooth Surface Finish
- High Tear Resistance & Reduced Yarn Crimp
- Non-Combustible, Non-Asbestos & Halogen-Free
The 4H satin weave structure allows yarns to float over multiple fibers, creating a fabric that conforms easily to complex shapes while maintaining excellent thermal performance.
Fabric Construction & Engineering Benefits
High Silica Cloth 4H Satin Weave is produced through a precision leaching process that converts glass fibers into ultra-high silica fibers. The 4-Harness Satin weave provides several engineering advantages:
- Minimal fiber distortion under thermal load
- Enhanced flexibility compared to plain & twill weaves
- Improved surface uniformity for coatings and laminations
- Better performance in curved, contoured, or layered insulation systems
This makes the fabric ideal for advanced thermal insulation assemblies and high-spec fire protection products.
