It has a flame, smoke, filling three major functions, no secondary pollution when burned, not only the good dispersion in the polymer, and also easy to produce a synergistic effect with other flame retardant additives, can be used in unsaturated polyester , epoxy resins, thermoplastics, synthetic rubber, composites, and other products. Pouring the production of unsaturated polyester high or low voltage electrical switch, make products with added aluminum hydroxide flame retardant, smoke and sex and arc resistance. Due to the high brightness white aluminum hydroxide more than 93%, there is a certain crystalline forms, and has a similar refractive coefficient polyester resin. Epoxy resin, aluminum hydroxide has a significant role in increasing the oxygen index can be used for sealing materials, casting parts, epoxy-glass fiber sheet and the like. In electrical terms, aluminum hydroxide can be reinforced epoxy anti-arc resistance and arc track resistance. By aluminum hydroxide in the production of epoxy resin filled transformers, insulation equipment, switching equipment, also has great development prospects. Addition of high amounts of aluminum hydroxide filled polyethylene and polypropylene, polyolefin plastics and other flammable, not only flame retardant, but also to high loading of the polyolefin for a composite molding process easier for the reaction, the product is improved tensile strength and impact resistance, it is widely used in the electrical conduit and the outer aspect of the device. Not only in the rubber can be made flame retardant, aluminum hydroxide, and can be used as a reinforcing agent and a styrene-butadiene rubber latex foam rubber carpet backing adhesive may also be used with a neoprene bedding. Aluminum hydroxide-resistant silicone rubber for improved tracking performance also plays an important role. Third, Packaging and storage Packaging: double coated woven bag, net weight 25kg or 40kg.
