Color concentrates, or master batches as they are also called, are frequently used to tint plastics. In special cases, they can be directly colored. Metal pigment pastes in mineral oils that are compatible with polymers or plasticizers or preparations in granulate form (pellets) in PE are used here.
If gold-bronze pigments are used, due to the high processing temperature, the use of coated, temperature resistance pigment powders is recommended.
