Product description: Control the production of the original crystal grains of aluminum hydroxide products through the seeding process, so as to obtain ultra-fine aluminum hydroxide powder with complete crystal grains, narrow particle size distribution and high whiteness, and keep the powder as much as possible during the drying process Exist in original crystal grains, it has good compatibility and dispersibility in polymer materials. It is an environmentally friendly inorganic flame retardant for rubber, plastics and other materials. This product is widely used in low-smoke halogen-free PC, PE, PP wire and cable master batch flame retardant filler, epoxy resin, polyurethane, unsaturated vinyl resin and fiberglass product filler, PCB flame retardant, chemical industry catalyst, highend Copper paper filler, toothpaste friction agent, medicine, cosmetics industry, special alumina raw materials and other special purposes.
Molecular formula: Al(OH)3
Sexuality: Aluminum hydroxide. It is a kind of alkali, because it shows a certain degree of acidity, it can also be called metaaluminate monohydrate (HAlO2·H2O), but when the actual aqueous solution reacts with alkali, the tetrahydroxyaluminate Al(OH) is formed 4
Usage: The most widely used inorganic flame retardant additive. Widely used in lowhalogen smokefree PC, PE, PP wire and cable master batch flame retardant filler, epoxy resin, polyacrylate, unsaturated vinyl resin and fiberglass product filler, PCB flame retardant, chemical industry catalyst, Highgrade copper paper filler, toothpaste friction agent, medicine, cosmetics industry, special alumina materials and other special purposes
Package: Packed in plastic woven bag or composite bag lined with film, net weight 25Kg
