Quartz Fiber Sleeve
Ultra-High Purity Quartz Fiber Sleeves for Extreme Temperature & Electrical Protection
Quartz Fiber Sleeve is a high-performance tubular insulation product manufactured from continuous amorphous quartz fibers with SiO₂ ≥ 99.9%.
Designed for extreme temperature resistance, electrical insulation, and fire protection, quartz fiber sleeves deliver exceptional thermal stability, low thermal expansion, and superior dielectric performance in the most demanding industrial environments.
Quartz fiber sleeves are widely used in aerospace, electrical, semiconductor, furnace, and high-temperature industrial applications where contamination-free, non-combustible insulation is required.
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
- Excellent Dielectric Strength & Electrical Stability
- Low Thermal Expansion & Minimal Shrinkage
- High Thermal Shock Resistance
