Rock Wool is produced by melting mix of basalt,limestone&coke in a special vertical furnace at very high temperature(about1500°C).Then the molten rock is made into thin fibers through a high speed centrifugal machine. After adding certain amount of binder,dust proof oil,silicon oil and mechanical operations,rock wool fibers are then processed to be the final desired product with specified physical and chemical Properties and specifications.

Advantage

1.rock wool with Longer life, permitting re-use after removal during maintenance

2.rock wool with Higher thermal performance, as it is made out of rich siliceous Rockwool. 

3.Environment friendly, as there is no feathering (which normally pollutes the environment). 

4.Uncontaminated, as manufacturing is a totally dry process. 

5.Non-wicking

6.Superior compressive strength. 

7.Excellent resistance to vibration & jolting 

Application

1.Petrochemical industry -- heat insulation and sound absorption of equipments for petroleum industry, power   

  industry and chemical industry.

2.Construction industry -- heat insulation and sound absorption of partition, curtain wall, roofs and fences for

  construction.

3.Mining industry -- heat preservation and fireproof for industrial kiln, oven, large-caliber storage tank and shipping.
