Quartz Fiber Braided Sleeve
Ultra-High Purity Quartz Fiber Braided Sleeve for Extreme Temperature & Electrical Protection
Quartz Fiber Braided Sleeve is a high-performance tubular insulation sleeve manufactured from continuous amorphous quartz fibers with SiO₂ ≥ 99.9%.
The braided construction provides excellent flexibility, expansion capability, and mechanical protection, making it ideal for thermal insulation, electrical cable protection, and fire-resistant sleeving in extreme environments.
Compared to fiberglass and high-silica sleeves, quartz fiber braided sleeves offer superior purity, lower thermal expansion, and outstanding dielectric stability, ensuring long-term performance in aerospace, semiconductor, and high-temperature industrial applications.
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
- Braided Construction for Flexibility & Expansion
- Excellent Dielectric Strength & Electrical Insulation
- Low Thermal Expansion & Minimal Shrinkage
- High Mechanical Strength & Abrasion Resistance
- Non-Combustible, Non-Asbestos & Halogen-Free
Quartz fiber braided sleeve maintains structural integrity and insulation performance even under repeated thermal and mechanical stress.
Braided Construction Benefits
The tubular braided design offers:
- Excellent flexibility for routing over complex shapes
- Expandable structure for easy installation over cables, hoses, and pipes
- Uniform wall thickness for consistent thermal protection
- Strong fiber interlocking for durability and long service life
This makes it ideal for dynamic applications and tight installation spaces.
