Hongda Fangyuan glassfiber is a type of fiber which is a man-made mineral fiber. Use of imported equipment, the U.S. technology, selected by broken glass as the main raw material, with a number of soda ash, borax and other accessories, the molten glass by centrifugation diameter of 3.5um 5.5um cotton wool blown glass micro-fiber, commonly known as glass wool , fiber and fiber entanglement between the interchange, with a large number of internal and external connectivity of the tiny pores and holes, so it is regarded as porous materials, with physical light and low thermal conductivity, thermal insulation and sound absorption performance, non-combustible, corrosion-resistant, non-toxic not afraid of moth-eaten, do not stab the skin, water-repellent l rate, and has good chemical stability, etc., is the production of sealed lead-acid battery separator glass fiber adsorption, filter paper, insulation paper, an ideal material, but also VIP (Vacuum insulation board) the material of choice. Is now recognized as superior performance of the insulation, silencers, an ideal material for insulation.
