Shandong taixing is an Aluminium Hydroxide ( Al(OH)3 CAS No. 21645-51-2 ) China manufacturer with highy quality and low price since 1998. We produce several types Aluminium Hydroxide, including precipitated aluminum hydroxide, Aluminum hydroxide (ground type), Low-viscosity Aluminum Hydroxide, these products can be used as flame retardant in plastic and rubber products .
Fine Precipitated Aluminium Hydroxide.( Al(OH)3, CAS No. 21645-51-2 ) is one type ATH with ultrafine particle size, regular crystal structure, high-purity, high whiteness, low surface activity and small specific surface area, Fine Precipitated Aluminium Hydroxide. can be widely used in various of processing technology.
Aluminum hydroxide (ground type, ( Al(OH)3 CAS No. 21645-51-2 ) is made of wet aluminum hydroxide powder by drying, grinding and sieving to get various grades with different particle sizes. Aluminum hydroxide is used as environmentally-friendly halogen- free flame retardant additives in a wide variety of applications.
Low-viscosity Aluminum Hydroxide ( Al(OH)3 CAS No. 21645-51-2 ) behave as flame retardant filler in pouring sealant, BMC,SMC and other industries. Compared with ordinary aluminum hydroxide, its particle size distribution is narrower and more concentrated, the viscosity is lower. Low-viscosity Aluminum Hydroxide is divided into four grades according to particle size.
