Audited Supplier Product Description
High quality rock wool with natural rocks as the main raw material, by weight, the ratio of cupola melting is higher than 1450 ºC, from the four rollers centrifuge high-speed optical fiber, the method is placed evenly spray adhesive cotton, and then curing, cutting into different specifications and usages of the product.
High quality rock wool has four characteristics: strong resistance to high temperature, good hydrophobic property, high corrosion resistance and low thermal conductivity, can be in the petroleum chemical industry, power plants and other industrial boiler, stove, distillation tower, valve, pipe and other equipment to provide the highest level of protection, resist heat and energy loss, avoid fire, noise and other harmful effects.
Buildings and Industries high-temperature rock wool products include:
- high quality rock wool board for Buildings and Industries use
- high quality rock wool blanket
- high quality rock wool pipe
