The glass wool product is placed in the glass of the meltdown appearance proceed the fiber turn and spray the resin of solid that draw the hot silk wadding form material, then turn through hot solid the deep processing handles and can also make into the series and various products. It has the performance of fire-preventing???on-toxic???ntisepsis???ight volume-weight???ow heat conduction factor???ood chemistry stability???ow water absorption coefficient and good hydrophpbic coefficient. Currentlly, it is the most superior heat preservation and sound absorption material generally accepted by people. This kind of material which can be make into board, tube, blanket , is widely used for insulation and heat preservation of building, chemistry, electron, electric power, metallurgy...etc, it has the following merits: the cost is lower, the function of hydrophpbic coefficient is good, enriching the flexibility, the soft degree is good; can affix aluminum foil to the surface, light volume-weight, non-combustible and prevent fire, chemistry stability is good; The application is wide, the specification of product is stable.
