  • Gloss reduction of plastics by media blasting
    Publication number: 20020119289
    Abstract: An unpainted thermoplastic material is provided. The unpainted thermoplastic material includes a microscopically deformed surface having a gloss less than about 3.0. A method of reducing gloss of a formed thermoplastic material is also provided. The method includes impacting a surface of the formed thermoplastic material with a particulate so as to effect light reflecting properties of the surface. The surface is microscopically deformed such that the light reflecting properties provide a gloss of less than about 3.0. The particulate is selected from the group consisting of baking powder, ice, sand, glass beads, and subliming particles.
