Glass fiber is a high-performance inorganic non-metallic materials . Components of silica, alumina, calcium oxide,boron oxide, magnesium oxide sodium. It uses marble as raw materials at high temperature-melting,lamp working, winder,weaving and other technology, Finally a variety of products. Glass fiber characteristics: 1)High tensile strength, elongation small(3%) 2)Coefficient of elasticity, rigidity good. 3)Flexibility within the limits of elongation and tensile strength of a large quantity of high impact energy is absorbed large . 4)For the inorganic fibers , a non-flammable, and good chemical resistance . 5)Absorbent small. 6)Scale stability , heat resistance are excellent. 7)The processing of the best , make stocks,beam carpets, weaving and other forms of products . 8)Through transparent light . 9)Resin and then of good surface treatment agent of development completed.
