Glass wool fibers belonging to a category, is a man-made mineral fibers using quartz sand, limestone and other natural minerals as the main raw material, with some soda, borax and other chemicals into the glass melt. In every other state, by means of force, blowing standard thrown into flocculent fine fibers, for interchange between the fiber and the fiber, intertwined with each other, showing many of the small gap. This gap can be regarded as void. Thus, the glass wool can be regarded as a porous material, with excellent thermal insulation, sound absorption performance.

Under the effect of centrifugal force, thrown into a molten glass fiber. Thereafter, a mixed gas under the action of high velocity, into a fiber drawing glass fibers, glass fiber webs in the landing set belt while spraying the binder, and then compacted, cured, cross-cutting, slitting formed some specifications of the products, and finally compressed bales, packaging and storage containers.
