Pigment Powder Mixtures
Pigment Powder Mixtures for plastics are chemical compounds divided into microscopic particles that have their own color and are intended to color a certain thermoplastic. Factors such as thermal resistance, migration, hiding power, approval for food contact, among others, characterize the different types of pigments available on the market.
The correctness of a certain color and the compatibility with the processing of a specific virgin or recycled thermoplastic depend on the skills of professionals of colorists.
Tonality, pigment origin, weather resistance, light resistance, approval for food contact, compatibility with the vehicle, among others, are presuppositions to be determined prior to the development of a certain color.
Pigments in Pigment Powder Mixtures can be of synthetic origin (manufactured or refined materials), organic (originated in plants or animals) and inorganic (mineral origin). All have primary colors that can be mixed with each other in order to obtain specific shades or treated in order to minimize environmental impacts.
White pigment, for example, has as its main component TiO2 (titanium dioxide), a mineral extracted from the soil and treated in order to neutralize the interaction effects between the respective constituent elements (aluminum and potassium hydroxide) and polycarbonate.
