SiO2 fiberglass fabric
Introduction
Its fiber is made of crystal material (SiO2) after refining treatment that is based on high tempersture melting. It is special structural and excellent performance, that is widely used in aerospace, aviation, electonics, metallurgy, petrifaction, cable, electric machinery, atomic energy and so on, as ablative material, stuctural material, electrical material, termal insualtion material, wave permeable material etc..
Feature
High purity, high temperature resist, ablative resist, high insulation, corrosion resist, low expansion, anti heat wave, light weight, high strength, excellent dielectric properties, good chemical stability
