Superfine aluminium hydroxide

2017-08-21

　　Characteristic：The product is produced by chemical method, and has the advantages of high purity, uniform particle size distribution, low conductivity and low oil absorption rate. The finished product has better mixing properties, lower compound viscosity and thermal stability.Use:1, used as a flame retardant filler PVC, epoxy resin, polyester resin, polyurethane resin, PVC resin, wire and cable, electrical appliances and other products, with flame retardant and smoke, modified non-toxic properties after surface treatment of flame retardant and smoke, better filling effect.2. Used as filler for coated paper, surface coating and flame retardant paper. Coated paper has a smooth surface, rich luster and strong absorbability to ink.3, used as silicone rubber, composite insulators and other industries.
