stone wool insulation board is made of basalt and other natural minerals as the main raw materials. After melting the raw materials, a four-roll centrifugal is used to make the high-temperature basalt melt into discontinuous stone wool fibers with diameter 4~7μm . A certain amount of adhesive, dustproof oil and water repellent are added to the fiber, then through processes such as sedimentation, solidification, and cutting, a series of products with different densities are made according to different purposes . stone wool insulation board is suitable for thermal insulation and sound insulation of industrial equipment, buildings, ships, etc.

     Below is introduction of advantages of stone wool insulation board.
     1. Insulation
     stone wool fiber is long and flexible, and the shot content is low. It has low thermal conductivity and excellent heat preservation performance.
     2. Fire prevention
     The raw material of stone wool is natural basalt, which is a non-combustible building materials.
     3. Non-corrosive
     stone wool is chemically stable, with a PH value of 7-8, neutral or weakly alkaline, and has no corrosion to metal materials such as carbon steel, stainless steel, and aluminum.
     4. Safe, environmental friendly and energy saving
     stone wool does not contain asbestos, CFC, HFC, HCFC and other substances harmful to the environment. No mold or bacteria will grow on stone wool
     5. Sound absorption and noise reduction
     stone wool is an ideal sound insulation material. A large number of long fibers form a porous  structure, which determines that stone wool is a superior sound-absorbing and noise-reducing material.
     6. Moisture resistance
     In a relatively high humidity environment, the moisture absorption rate of stone wool is less than 0.2%; according to the ASTM1104 or ASTM1104M testing method, the moisture absorption rate is less than 0.3%.
     Above is the introduction of advantages of stone wool insulation board. Hope this can bring you some help.
