High whiteness aluminum hydroxide for filler (Carbonating process)
High whiteness(Reputated as China White), low oil absorption, good stability at room temperature and dehydrated to alumina while heating, to make the products have the function of flame retardant. Its a good flame retardant filler because that no toxic and corrosive gases were generated in thermal decomposition.It’s widely used in the solid surface, mould plastics, epoxy potting compound and other composite materials.
