Product Features:
Thermal insulation: thermal insulation is the basic property of rock wool products, the thermal conductivity is 0.03~0.040W/(m.K) in normal temperature(25C)
Combustibility: rock wool is inorganic fiber, non-combustibility. The grade is Non-combustibility A1.
Acoustic insulation: rock wool has excellent sound absorption property, the reason is it has porous structure, when sound wave go through rock wool, the friction creates because of the flow resistance, and some sound energy is absorbed by the fiber, and sound wave is blocked.
Chemical property: high acidity coefficient, excellent chemical stability and fiber durability.
Physical property: low density, excellent machinability.
Production Application:
Petrochemical industry: thermal and acoustic insulation for equipments of petroleum, electrical power, chemical industry
Building construction: thermal and acoustic insulation for partition wall, curtain wall, roof and building envelope.
Mining industry: fireproof and thermal insulation for industrial furnaces, ovens, large caliber tanks etc.
Shipping industry: thermal insulation for ships cabin, pipe etc.
