Quartz Fiber Tubular Braided Sleeve
Ultra-High Purity Quartz Fiber Tubular Braided Sleeve for Extreme Heat & Electrical Insulation
Quartz Fiber Tubular Braided Sleeve is a high-performance insulation sleeve manufactured from continuous amorphous quartz fibers with SiO₂ ≥ 99.9%.
The tubular braided construction provides excellent mechanical strength, flexibility, and uniform wall thickness, making it ideal for thermal insulation, electrical cable protection, and fire-resistant sleeving in severe operating environments.
Compared to knitted sleeves, the tubular braided quartz sleeve offers higher abrasion resistance, better dimensional stability, and superior mechanical durability, while maintaining outstanding thermal and dielectric performance.
Key Performance Advantages
- Silica (SiO₂) Content: ≥99.9% (Ultra-High Purity Quartz)
- Continuous Operating Temperature: Up to 1050°C
- Short-Term Temperature Resistance: Up to 1200°C
- Tubular Braided Construction for Strength & Stability
- Excellent Dielectric Strength & Electrical Insulation
- Low Thermal Expansion & Minimal Shrinkage
- High Abrasion & Mechanical Resistance
- Non-Combustible, Non-Asbestos & Halogen-Free
Quartz fiber tubular braided sleeve maintains structural integrity and insulation efficiency even under repeated thermal cycling and mechanical stress.
Tubular Braided Construction Benefits
The tubular braided structure offers:
- Uniform wall thickness for consistent thermal protection
- Smooth internal surface for easy installation over cables and hoses
- High mechanical strength for long service life
- Improved resistance to abrasion and external wear
This construction is ideal for static and semi-dynamic applications requiring durable thermal and electrical protection.
