Pigment Powder Mixtures
Pigment powders for plastics are chemical compounds divided into microscopic particles that have their own color in order to color a certain thermoplastic. For example, factors such as heat resistance, migration, hiding power, approval for food contact, and others characterize the different types of pigments available on the market.
Color Matching | Pigment Mixtures
The matching of a given color and the compatibility with the processing of a given thermoplastic, virgin or recycled, depend on the colorists’ skills.
Tint, pigment origin, resistance to weathering and to light, approval for food contact, compatibility with the vehicle, among others, are prerequisites to be determined prior to the development of a given color.
Types of Powder Pigments
The pigments that make up pigment mixtures may be synthetic (manufactured or refined materials), organic (plant or animal origin), and inorganic (mineral origin). All of them have primary colors and can be mixed together with the purpose of obtaining specific shades or treated in order to minimize environmental impacts.
The white pigment, for example, has TiO2 (titanium dioxide) as its main component, a mineral extracted from the soil and treated in order to neutralize the effects of interaction between its constituent elements (aluminum and potassium hydroxide) and the polycarbonate.
