HPQY is produced by drawing fiber (9 micron or 14 micron) from high
purity (SiO2> 99.95%; exclusive of binder) quartz rods.So quartz fiber has many superb properties : high purity, high
temperature resistance, ablation resistance,low heat-conduction,Anti-thermal Shocks, excellentdielectrical propertyandchemical stability. Primarily used as materials ofelectric insulation,heat insulation, composite reinforcement , etc. Typical products areaircraft nose, radome , rockettailpipenozzleand ablative material ofspacevehicle,etc. Otherwise some other quartz fiber products are available ,
such as fabric, tape,chopped strands, unwoven roving, rope,wool and
braided sleeving .
