Aluminum Hydroxide Filler for Artificial Marble Filler for Acrylic Solid Surface Hwf14 Hwf25 Hwf75

High whiteness aluminum hydroxide for filler

Product performance:

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.
Application:
It's widely used in the solid surface, mould plastics, epoxy potting compound and other composite materials.
