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 . 技术指标：Technical data 项目items 参数 data 纯度 purity % SiO2≥99.95 密度density g/m3 2.2 拉伸强度tensile strength GPa 3.6 弹性模量elastic modulusGPa 78 硬度 hardness 6-7 耐温thermal°C 1200 软化点softening point°C 1730 热膨胀系数 thermal expansivity°C?1 轴向axial direction：5.4×10?7 径向radial direction：5.4×10?7 电阻率resistivityΩ*cm 20°C，10 19 800°C，2*10 17 介电常数permittivity 3.78 损耗角正切值dissipation factor 0.0001 注：1.可根据客户要求提供特殊规格产品。2.以上数据仅供参考。 Mark: 1.Special product could be available based on customers' requirements.2.Reference data only, not for technical specifications.
