Introduction

Quartz fiber twistless yarn is of parallel cluster filament without twisting, which could be used directly as reinforcement materials, or as raw materials for twistless roving fabric and non-woven fabric(felt) 

Performance

1. Low dielectric properties: Dielectric Constant(Dk) 3.74, Dissipation Factor(Df) 0.0002. Excellent wave-transparent material

2. Ultra-high temperature resistance, long lifetime at temperature of 1050℃-1200℃, softening temperature 1700 ℃, thermal shock resistance, longer service life

3. Low thermal conductivity, small thermal expansion coefficient only 0.54X10^-6/K, which is a tenth of ordinary glass fiber, both heat-resistant and heat-insulated

4. High strength, no micro-cracks on the surface, tensile strength up to 3600Mpa, which is five times that of high silica fiber, 76.47% higher than that of E-glass fiber

5. Good electrical insulation performance, resistivity 1X1018Ω·cm~1X106Ω·cm at temperature 20 ℃ ~ 1000 ℃. An ideal electrical insulating material

6. Capable of long-term acidic, alkaline, high temperature, cold, stretching and other harsh working conditions, corrosion resistance

Applications

1. Wave-transparent material (missiles, radomes of aircraft & satellite, electronic countermeasure devices)

2. Stealth materials (aircraft, missiles, drones, fighters, bombers, ships, submarines, etc.)

3. High-performance printed circuit board material(high frequency  & high-speed PCB materials)

4. Ablation-resistant material (spacecraft thermal protection material, missile exhaust pipes)

5. High temperature resistance and heat insulation material (aircraft engine and fuselage fire proof, semiconductors and optical fiber manufacturing)

6. High temperature resistant catalyst carrier material (vehicle exhaust gas treatment, industrial air purifier)

7. Glass manufacturing (insulation material for automobile glass tempering furnaces)

8. High temperature and fake skeleton reinforcing material

9. Tooth post and fake skeleton reinforcing material

10. An ideal substitute for high silica, ceramic and E-glass fiber
