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