Features of Quartz Fiber
Superior High Temperature Resistance:
Long-term working temperature up to 1050℃~1200℃, softening point up to 1700℃. Excellent thermal shock resistance and ablation resistance, far better than ordinary glass fiber and high silica fiber cloth.
Low Dielectric & High Wave Transmittance:
Ultra-low dielectric constant and dielectric loss at high frequency, minimal electromagnetic signal attenuation. Perfect for 5G/6G radio frequency substrates, high-speed PCB and aerospace radar wave-transparent structures.
Excellent Physical Stability:
Ultra-low thermal expansion coefficient, outstanding dimensional stability, high tensile strength and flexible weaving structure, easy for cutting, laminating and composite molding.
Strong Chemical Corrosion Resistance:
Resistant to most acid and alkali corrosion, moisture-proof and weather-resistant, suitable for harsh industrial and outdoor extreme environments.
Full Product Series & Customization:
Complete specifications from 0.1mm to 0.28mm, multiple weave types available. Support customized density, width and special technical requirements for customer projects.
Weaving Process & Product Performance
Our quartz fiber cloth is woven from high-purity continuous quartz filament yarns with precise loom control. Adopting standardized plain, twill and satin weaving structures, each fabric features uniform texture, stable density, no broken yarn, no floating thread and excellent surface flatness.
Plain weave offers balanced tension and stable structure for general insulation and wave-transparent composite parts. Twill weave provides better flexibility and bending resistance for curved surface molding. Satin weave delivers smoother surface, higher compactness and better wave permeability, ideal for high-precision radar and electronic grade components.
