High silica fiber fabric
1. introduction
High silica fiber is heat-resist and soft material which is made of more than 96% SiO2. it is good temperature and corrosion resistant, insulation, dielectric properties, long time working in temperature reach more than 1000°C (instant 1400°C).
It is widely usage, such as heat insulation in aid, fire proof, filtration of hot sewage, electric insulation, anti-ablation and wave previous material for space craft, it can be provided in the forms of continuous yarn, sewing thread, rope, chopped strands and glass wool, braided sleeves and cloth etc..
2. characteristics
Silica content: more than 96%
Loss energy: less than 3%
Excellent heat-proofing and electric insulation
Soft and easy for designing to process
