Physical and Chemical Properties | Chemical properties When glass fiber is used as a reinforcing material for reinforced plastics, the biggest feature is its high tensile strength. The tensile strength is 6.3~6.9g/d in the standard state and 5.4~5.8g/d in the wet state. Density 2.54. Good heat resistance, no effect on strength when the temperature reaches 300 ℃. It has excellent electrical insulation, is a high-grade electrical insulation material, and is also used for thermal insulation materials and fire shielding materials. It has strong chemical resistance to inorganic and organic acids impregnated with hydrofluoric acid and phosphoric acid. |
Use | Uses Long fiber is used as electrical insulation material, fiber reinforced plastic, shielding material, filter and abrasive reinforcement material, etc. Short fibers are used as heat insulation, heat preservation, sound insulation materials, anti-corrosion materials and battery materials for buildings, cold storage, industrial devices, etc. |
