High whiteness (reputed as 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 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, mold plastics, epoxy potting compound and other composite materials.
