Wooden box package
Product feature
- Made from pressed and high-temperature treated (up to 2300 °C) rayon carbon fiber felt
- Ultra-low thermal conductivity (≤0.25 W/(m·K) at 1000 °C)
- Very low bulk density (0.2 g/cm³)
- High purity available (ash content ≤20 ppm)
- Maximum operating temperature of 2400 °C
Product advantage
- Provides outstanding high-temperature insulation, minimizing heat loss
- Maintains dimensional stability and strength in extreme thermal cycling
- Lightweight yet mechanically robust, easing handling and installation
- Excellent oxidation and corrosion resistance for long service life
Product application
- Insulation in furnaces for growing silicon ingots (solar & semiconductors)
- Thermal management in sapphire crystal growth and fiber optic production
- High-temperature insulation in various heat-treating and sintering furnaces, including those for Metal Injection Molding (MIM)
