商品详细描述
高纯石英纤维(SiO2> 99.95%)是由高纯石英棒熔融拉制而成的连续长纤维。其具有高纯度、耐高温、耐烧蚀、低导热、抗热震、优良的介电性能和良好的化学稳定性等。主要用作电绝缘材料、隔热材料和复合材料的增强体。用于制造飞机机头、雷达罩、火箭的尾喷管、空间航天器的烧蚀材料等。另我们还可根据客户需要提供其他石英纤维产品，诸如布、带、短切纤维、无捻粗纱、绳、棉、编织套管等。
HPQY is produced by drawing fiber (9 micron to 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 stability. Primarily used as materials for electric insulation, heat insulation, composite reinforcement, etc. Typical products are aircraft nose, radome, rocket tailpipe nozzle and ablative material of space vehicle, etc. In addition, some other quartz fiber products are available, such as fabric, tape, chopped strands, unwoven roving, rope, wool and braided sleeving .
