Glass fiber raw materials and product characteristics:
1. The main raw materials for the production of glass fiber are: quartz sand, alumina and pyrophyllite, limestone, dolomite,  boric acid, soda ash, mirabilite, fluorite.
2. The main components of glass fiber are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc.
3. Glass fiber characteristics: melting point 680 ℃ boiling point 1000 ℃, density 2.4~2.7g/cm3
4. Glass fiber has high temperature resistance, no effect on strength when the temperature reaches 300℃, no loss of                strength below 500℃, non-combustible, corrosion resistance, good heat and sound insulation, high tensile strength, and good electrical insulation.
