Rock Wool Board
Rock wool board is basalt as main raw material, by high temperature melt processing of mineral fiber board. Products because of good fire prevention, thermal insulation, sound-absorbing noise reduction, green environmental protection and other characteristics, widely used in petrochemical, textile, metallurgy, electricity, transportation, building agriculture and other fields.
