Pearlescent Pigments

Pearlescent pigments in plastics are special effect additives that impart a pearly or metallic sheen to plastic products. These pigments typically appear as partly translucent powders formed by depositing titanium dioxide and/or iron salts onto mica, layered with metal oxides. Key features include their ability to produce shimmering, iridescent finishes, enhance aesthetic appeal, and provide unique color variations depending on the angle of light and the viewer's perspective. They are suitable for applications in automotive interiors, cosmetics packaging, and consumer electronics. 

Alternatives to pearlescent pigments include metallic pigments and interference pigments. Sub-types include synthetic mica-based and natural mica-based pigments.
