high temperature centrifugal glass wool board

Introduction

Glass wool board is one category of glass fiber, a kind of man-made inorganic fiber. With quartz sand, limestone and dolomite as main raw material, companying some sodium

carbonate and sodium borate will melt into glass. In the state of melting, with external force, it will be spun into cotton

shaped fine fiber, with fiber and fiber crossing and twisting together, showing lots of tiny gaps among them, which can

be regarded a pore space. So glass wool can be treated as multi-pore material, with an excellent thermal insulation and sound absorption property.

It is a kind of platy material made through adding phenolic resin adhesive into superfine wool felt, solidifying under heat

and pressure. PVC film or aluminum foil can be sticked on the surface. It has characteristics of light volume weight, big

sound absorption coefficient, excellent chemical stability of inflaming retarding.

Applications
