Product Feature
Quartz fiber is made of high purity silica and natural quartz crystal. The purity is 99.99% and the density is 2.2g/cm3. The tensile strength is 7gpa and the tensile modulus is 70gpa. It has heat resistance, corrosion resistance and softness. High strength retention, dimensional stability, thermal shock resistance, chemical stability, light transmittance and electrical insulation at high temperature. The diameter of reinforcing filament is 4-10 μ M. the diameter of quartz fiber varies with its application, about 0.7-10 μ M.
