The field of usage of rock wool
The product is widely used for the heat insulation and sound absorption in building field and heat preservation of pipes, wires and so on. We make much progress in producding products for make it good for human. Thus this product has excellent properties, such as elasticity, pliability, handle tenderness, little soft flocks.
