Rock wool board

Product description:
Rock wool board is made by melting the high standard basalt. The product has good properties of low density, low heat conductivity, good performance of sound absorbing, does not burn, good chemical stability. Besides the common properties of rock wool, there are still many other good characteristics as: waterproof, thermal insulation, cold insulation, dose not deliquesce even in moist condition.

Features:
Easy-cut and easy to install
Thermal insulation
Light weight
Sound absorption
Environmental friendly

Application
Rock wool board has wide rang applications: construction, petroleum, power sector, metallurgy, textile industry , national defense , communication and translation , boiler , flue heat exchanger , draught fan , thermal insulation and sound absorbing of shipping and automobile manufacturing .
Petrochemical industry : thermal insulation and sound absorption of petroleum industry , power plant , chemical industry etc.
