Description
Aluminum hydroxide (ground type) is made of wet aluminum hydroxide powder by drying, grinding and sieving to get various grades with different particle sizes. Alumninum hydroxide is environmentally-friendly halogen free flame retardant, can be used as flame retardant and filler in a wide various applications, such as SBR latex compound, synthetic rubbers, epoxy resins, unsaturated polyester resins,other plastic and the filler for toothpaste,artificial marble, coating, adhesives etc.
