Specifications: glass fiber 1.Good insulation 2, heat resistance 3, corrosion resistance 4, high mechanical strength........ Glass fiber temperature than the organic fibers, non-combustible, corrosion resistance, heat insulation, sound insulation (especially wool), high tensile strength, good electrical insulating properties (such as E-glass fiber). Brittle, poor wear resistance. The glass fiber is mainly used for electrical insulating materials, industrial filtration materials, corrosion, moisture, heat insulation, sound insulation, shock absorption materials. Also as a reinforcing material used to manufacture reinforced plastic (see color pictures) or reinforced rubber, reinforced gypsum and enhanced cement and other products. Organic material coated glass fiber can improve their flexibility to made of packing cloth, window screening, paste, cover cloth, protective clothing, and absolute power, insulation materials.
