Характеристики











Glass wool is a kind of glass fiber and a kind of artificial inorganic wool. Adoping such natural ores as quarts sand, Iimestone ect as the main ingredients and then coordinating with some chemical materials such as Soda ash and borax etc, the glass is hence melted . under the melting condition, floccular fibril is made via external force and blow.The fly-over crossing is taken on between fibers and then they are intertwined. Thus many fine gaps are showed out. These gaps can be regarded as pore spaces. Therefore, the glass wool can be taken on as porous material with excellent thermal insulation and sound absorption performance.
