? main raw materials/rock wool blanket ?
?
?
1.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.
?
?
2.Advantage:
?
1. Quality lighter
?
2. Low thermal conductivity
?
3. Heat insulation
?
4.Good workability
?
5. Excellent tensile strength
