Glass wool sandwich glass wool is a unique centrifugal technology, the molten glass fibrosis and to thermosetting resin-based binder formulation environmentally friendly processing of products, is a glass fiber having a diameter of only a few microns made into a plane resilient glass fiber products. Because wool color steel have lots of tiny voids with thermal insulation, sound absorption and security and so on, it is the best material for building fire insulation, sound absorption. Advantages: A1 class fireproof, noncombustible permanent antimicrobial mildew, anti-aging anti-corrosion, to ensure a healthy environment and sound absorption, can effectively prevent the propagation of sound low moisture absorption, physical properties of stability high shock resistance, and high durability Applications: Widely used in : Clean purification plant, the combination of housing, roof and floor, interior partitions, car Gar paint room and freezing cold storage and so on. Such as: pharmaceuticals, electronics, food, beverages, fresh vegetables, large refrigerator and civil construction and other interior use.
