Raw materials and their applications: Glass fiber is higher in temperature resistance than organic fiber, non-flammable, corrosion-resistant, heat-insulating, sound-insulating, high tensile strength, and good electrical insulation. However, it is brittle and has poor wear resistance. Industrial filter materials, anti-corrosion, moisture-proof, heat-insulating, sound-insulating, shock-absorbing materials. It can also be used as a reinforcing material for the manufacture of reinforced plastics (see color pictures) or reinforced rubbers. As a reinforcing material, glass fibers have the following characteristics. These characteristics make the use of glass fibers far more extensive than other types of fibers.
