U.S. Produces High Density and Overweight Plastics

A U.S. company produces a high-density, overweight plastic. This high-density plastic is made by adding a heavy mineral ultrafine particle in proportion to a plastic raw material, thereby greatly increasing the density and specific gravity of the plastic. The plastic is easy to process, the molding time is short, the quality of the surface processing can reach the finish of the metal, and can be used to replace some alloys to manufacture some high-strength mechanical parts.
