Quartz Fiber Powder

Quartz Fiber Powder is white powder made from quartz glass fiber with SiO₂ content ≥99.95% via special processes including soaking, cutting, drying, grinding and screening. The raw fiber diameter is 5~10μm. It features outstanding electrical insulation with low dielectric constant and ultra-low dielectric loss. It has excellent thermal resistance, which can be used continuously at 600~1050℃ and withstand instant high temperature up to 1700℃. Its tensile strength is second only to carbon fiber, with high whiteness, zero combustible content and low moisture.

• Widely applied in aviation
• aerospace
• military industry
• semiconductors
• high-temperature thermal insulation and high-temperature filtration. It can also be used as filler for high-performance composite materials in high-end insulating components
• heat-resistant parts and special sealing materials.
