High Silica Braided Sleeve | Silica Content >98%
High-Temperature Silica Braided Sleeve for Cable, Hose & Pipe Protection
High Silica Braided Sleeve (>98% SiO₂) is a premium high-temperature protective sleeving designed to provide exceptional thermal insulation, flame resistance, and mechanical protection for cables, hoses, pipes, and wiring exposed to extreme heat.
Manufactured from continuous high-purity silica fibers and braided into a flexible tubular sleeve, this product offers excellent expandability, abrasion resistance, and long-term stability in harsh industrial environments.
Designed for continuous operating temperatures up to 1000°C with short-term exposure up to 1200°C, high silica braided sleeve is widely used in power plants, foundries, furnaces, aerospace, metallurgy, and fire-resistant electrical systems.
Key Performance Advantages
- Silica Content: >98% (Ultra-High Purity SiO₂)
- Continuous Temperature Resistance: Up to 1000°C
- Short-Term Heat Exposure: Up to 1200°C
- Flexible Braided Tubular Construction
- Excellent Abrasion & Cut Resistance
- Low Thermal Conductivity
- Non-Combustible, Non-Asbestos & Halogen-Free
The braided sleeve structure allows easy installation over cables and hoses while maintaining strong protection against radiant heat, molten splash, and mechanical wear.
Sleeve Construction & Engineering Benefits
High Silica Braided Sleeve is manufactured using high-purity silica yarns produced through a controlled leaching process to achieve >98% silica content. The braided tubular design provides:
- High flexibility and expandability
- Uniform wall thickness for consistent insulation
- Superior resistance to fraying and abrasion
- Easy installation over irregular shapes
Compared to flat tapes or fabrics, braided sleeves deliver 360-degree protection for cylindrical components.
