Glass wool felts

Product introduction

Glass wool is a kind of glass fiber and a kind of artificial inorganic wool. glass wool felts Adopting such natural ores as quartz sand, limestone, etc. 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 fiber 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.
