Specifications
Rock Wool BoardNon-combustibility A1 GB Testing
Heat and sound Insulation
Prevent fire
No smoke and poison
Main components:
Rock wool uses basalt and other natural ore, as the main raw materials. It fused into a fibrous after the high temperature, added suitable amount of binder, then made by curing processing.
Advantage:
1. Quality lighter
2. Low thermal conductivity
3. Heat insulation
4.Good workability
5. Excellent tensile strength
6.Good corrosion resistance and can be use for long time
7.Excellent sound-absorbing performance
8. Good seismic performance
Application:
1. Petroleum, metallurgy, electric power, machinery, chemical industry equipment insulation, for sound-absorbing noise reduction
2. Building partition wall, curtain wall, fire doors, elevator well, roof and retaining heat insulation, for sound-absorbing noise reduction,
3. Industrial furnace heat insulation, oven, large diameter storage tank and heat preservation of the ship, for fire protection.
