Flame Retardant Aluminum Hydroxide

High purity flame retardant aluminum hydroxide high whiteness (has the reputation for chinese whiteness), low oil absorption, steady in room temperature and dehydrated to alumina while heating, to make the products have the function of flame retardant. It`s good flame retardant filler because that no toxic and corrosive gases were generated in thermal decomposition.
