Rock wool board is made of basalt and other natural ore as main raw material, melted into fiber at high temperature, added with proper amount of binder and cured and processed. It is widely used in shipbuilding, metallurgy, electric power, construction and other industries, and has good Thermal insulation and sound insulation. The construction and installation are convenient and the energy-saving effect is significant, with a high performance-cost ratio.
Rock wool board features :
1. Appearance quality: The surface is smooth and there must be no damage or damage to the utility.
2, combustion performance: not flammable.
3, heat load shrinkage temperature: 643 degrees.
4, hygroscopicity: 3.9%.
5. Organic matter content: 2.9%.
