Metallic Looking Plastics With New Silver and Colored Aluminum Pigments

摘要

s The application of aluminum pigments in plastics presented a problem in the past because of the flow line they caused in injection molded parts. By using large size aluminum pigments, with an average particle size of 60μ to 330 μ and larger it is possible to avoid these flow lines and produce metallic looking plastic parts. This concept was taken one step further by depositing colorants on these large size aluminum pigments, thereby creating a blue, green, and golden metallic looking colorant that can be used in plastics without flow lines. These pigments offer exceptional styling effects by themselves and in combination with other colorants including bronze pigments.
