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, excellent dielectrical property and chemical
Primarily used as materials of electric insulation, heat
insulation, composite reinforcement , etc.
Typical products are aircraft nose, radome , rocket tailpipe nozzle
and ablative material of space vehicle,etc.
Otherwise some other quartz fiber products are available , such as
fabric, tape,chopped strands,
unwoven roving, rope,wool and braided sleeving .
