Temperature Resistance 99.95% SIO2 Quartz Twisted Yarn
Product Description
It is made of multistrands twisted yarn from single fiber diameter 5.5um or 7.5um, 8~10Tex, which is blown by flame of 99.95% SiO2 quartz article.
The finished production:51Tex, 73Tex, 95Tex, 131Tex, 190Tex, 220Tex, 358Tex. The Twist is 70 or 140 per meter,breaking strength ≥0.35N/Tex,temperature tolerance 1200ºC, melting point 1710ºC. With the characteristic of high purity, high temperature tolerance, corrosion resistance, low thermal conductivity and good stability, it is widely used in space aircraft, missle radome special filter bag and other fields, and can also be used for fabric, belt, pipe, needled mat and stitched mat.
