Mineral wool board


Mineral wool blanket, board, used for thermal insulation.

More details


Rock Mineral wool board use superior melted basalt and diabase as the main raw material, through advanced centrifuge system of four-roller cotton process which pulls melted basaltic rockwool into a 4 ~ 7μm non continuous fibers, followed by adding a certain amount of binder, dust laying oil, water repellent before settlement folding, curing, cutting and other processes, finally made into the products of different density. 

It is widely used by shipbuilding, construction, Petroleum, electric power, chemical industry equipment’s thermal insulation and acoustic noise reduction.
