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.
Claims22
An unpainted thermoplastic material, comprising:
- a microscopically deformed surface having a gloss less than about 3.0.
A method of reducing gloss of a formed thermoplastic material, comprising:
- impacting a surface of the formed thermoplastic material with a particulate so as to effect light reflecting properties of said surface.
A method of making a plastic article, comprising:
- forming an extrudate of thermoplastic material;
- forming the plastic article from said extrudate;
- and
- microscopically deforming a surface of the plastic article to reduce a gloss level of said surface.
An instrument panel section, comprising:
- a skin of unpainted thermoformed thermoplastic material.
