Rigid high density external wall insulation fire resistance rock fibres mineral wool insulation price
Rock wool products are made from natural rock such as basalt and dolomite. The natural rock are melted into melts in cupola at a very high temperature about 1500°C. And the melts lava is then pour to high speed spinners through which the melts get into fibers. At the same time, the phenolic binder containing silicon and mineral oil etc are sprayed onto the surface of each fiber homogeneously.
Rock wool board is suitable for heat insulation, fire prevention and sound absorption and noise reduction on the surface of storage tanks, containers, boilers and catheters with flat or large diameter curved surfaces. The fiber structure of the product makes the product have good dimensional stability and compression resistance.
Rock wool board has four perfect characteristics: high temperature resistance, good hydrophobicity, high corrosion resistance and low thermal conductivity, can provide the highest level of protection against heat and energy loss in the field of petrochemical, power plants, industrial tanks and other industrial equipment, to avoid fire, noise and other harmful effects.
