High Silica Cloth 5H Satin Weave | Silica Content >98%
Ultra-Flexible High-Temperature Silica Fabric for Critical Thermal & Fire Protection
High Silica Cloth 5H Satin Weave (>98% SiO₂) is an advanced high-temperature textile engineered for applications requiring maximum flexibility, ultra-smooth surface finish, and superior thermal stability.
Manufactured from continuous high-purity silica fibers and woven in a 5-Harness (5H) Satin weave, this fabric offers lower yarn crimp, higher drapeability, and improved load distribution compared to 4H satin, twill, and plain weave silica fabrics.
With continuous temperature resistance up to 1000°C and short-term exposure up to 1200°C, 5H satin weave high silica cloth is widely used in aerospace insulation systems, advanced fire barriers, thermal shielding, and complex-geometry insulation assemblies.
Key Performance Advantages
- Silica Content: >98% (Ultra-High Purity SiO₂)
- Continuous Operating Temperature: Up to 1000°C
- Short-Term Heat Resistance: Up to 1200°C
- Exceptional Drapability & Conformability
- Ultra-Smooth, Low-Friction Surface
- Reduced Yarn Crimp for Improved Strength Retention
- Non-Combustible, Non-Asbestos & Halogen-Free
The 5H satin weave structure allows yarns to float over more intersections, producing the highest flexibility and smoothest surface among woven silica fabrics.
Fabric Construction & Engineering Benefits
High Silica Cloth 5H Satin Weave is produced through a precision leaching process that converts glass fibers into ultra-high silica fibers (>98% SiO₂). The 5-Harness Satin weave delivers distinct engineering benefits:
- Superior drapeability for tight radii and complex contours
- Reduced internal stress concentration at elevated temperatures
- Improved coating and lamination adhesion due to smooth surface
- Enhanced performance in multi-layer insulation and aerospace systems
This makes 5H satin weave silica cloth the preferred choice for high-specification thermal protection designs.
