Fiberglass is a glass product made by combining low alkali glass materials and melting them at high temperatures, whereby thin fibers are made through bushing. KCC Fiberglass is used as a reinforcing material for FRP (Glass Fiber Reinforced Plastic) for its high strength, nonflammable property, excellent chemical resistance, electric insulation property, heat resistance and durability. It is widely used as a composite material for the development of new materials.
