Product details

Rock Wool Products are manufactured with basalt as main ingredient,made into inorganic fiber in high speed centrifugal machine after melting, A certain amount of cementing agent, rustproof oil, silicon oil is added into the raw materials which is made into rockwool board, rockwool pipe shell, etc. (according to different customer requirement)
Moisture-proof aluminum foil, black (white) glass fiber cloth, sandwich glass fiber felt and moisture-proof facings can be stuck on surface of rock wool board.


1. High quality and extra fine, low slag-ball content and low coefficient of heat conductivity.

2. Wide range of bulk density (40kg-200kg/m3), wide range of specifications with all data being within/better than national standards.

3. Wide range of applications for construction, petroleum,electric power, metallurgy, textile, national defence, transportation ans other industries. Ideal material for heat insulation and sound insulation of industrial facilities such as tank, boiler, flue, heat exchanger, blower, vehicles and ships etc.

4. Owing to its large-scale production and advanced technology the products are salable in home market, especially for large and key projects. The products are also sold to more than 10 countries/regions abroad.
