Brief Introduction
Rock wool blanket uses high-quality basalt as raw material whose melting point is above 1000 ºC and has good effects on heat insulation and sound absorption. It has good properties of fire resistance, pest proof, corrosion resistance, stable chemical property and free-asbestos and safe to human bodies.

Features
1.Small coefficient of heat conductivity and good capability of heating preservation.
2.Outstanding effect of energy-saving.
3.Excellent fireproof capability. Excellent sound absorption and sound insulation capability.
4.Green thermal insulation materials and no harm for body.
5.Waterproof.
6.The folded rock wool board with certain compression resistance has greater drawing strength, and it does not tend to peel off and has excellent improved durability.
Application
Rock wool insulation materials are widely used in construction wall, roof, industrial furnace, oven, heat-treating equipment, storage tank, storage groove, power house, flue, petrifaction and oil refining equipment and all kinds of keeping-warm and heat insulation pipelines.
