Aluminum hydroxide is the most widely used and cost-effective general inorganic flame retardant filler. It absorbs heat and cools down and dilutes combustible gas when heated and decomposed, with excellent flame retardant, smoke suppression and smoke elimination effects. It has high whiteness, good filling performance and low price with strong processing adaptability, being the mainstream basic flame retardant filling raw material in general rubber and plastic, coating and fiberglass reinforced plastic industries.
