PAN-Based Carbon Fiber Soft Felt

1. Core Performance Factors

• High Purity: High-purity grades with ash content kept below 20 ppm, to prevent contamination during the growth of sensitive semiconductors.
• Thermal Efficiency: Low thermal conductivity of 0.1-0.13 W/(m*k) at 25°C maintains stable temperature gradients and reduces energy loss.
• Heat Resistance: Reliable stability even in environments exceeding 2200°C.
• Structural Integrity: Our air-jet forming process keeps fibers even. This prevents the hotspots and material fatigue that often disrupt long growth cycles.  

3. Applications

Semiconductor Production: This is a key insulation layer for monocrystalline silicon and SiC crystal growth furnace setups.

Optical Fiber Communications: Ideal for use in sintering furnaces, drawing towers, and high-temp rod production.

Advanced Research: Trusted in sapphire growth furnaces and specialized high-temperature purification systems.

4. Why Choose VETEK?

Faster Throughput: By utilizing low-specific-heat materials, we’ve made thermal cycling much faster—this directly increases your daily throughput.

Reliable Shielding: Our production focus is on strict fiber density control; we eliminate weak spots so you get reliable shielding across the entire chamber.

HPSI Standards: For HPSI and RF processes, our high-purity standards are specifically engineered to handle those sensitive, high-resistivity requirements.
Simple Installation: Since the material is naturally flexible, it can be precision-cut to fit complex geometries, which really helps simplify the whole installation process.
