This item Hoprime quartz fiber is made of heating high purity quartz rods with an oxyhydrogen flame. Then, filaments are drawn out of the quartz rod, creating homogeneous, non-porous, continuous, amorphous, ultra pure quartz fiber.

The Hoprime quartz fiber twisted yarn is assemblies of continue high purity (SiO2≥99.99%）quartz filament(diameter 7.5um) gathered into strands ( forming package + carton box),then processed with varying levels of twist and ply . Quartz fiber yarn has many superb properties: high purity, high temperature resistance,ablation resistance,low heat-conduction,anti-thermal shocks,excellent dielectrical property and chemical stability.
