Colortherm® Red 520

Colortherm® Red 520 by LANXESS is a heat-stable, micronized iron oxide pigment. It does not migrate and is very light-fast and weather stable. It shows exceptionally low copper and manganese content, which makes it especially suitable for the coloring of natural- and synthetic rubber compounds. It possesses good dispersibility, even in processes which have short dwell times and relatively low shear forces. It is easy to break down and distribute to reach its final tinting strength quickly. It is developed particularly for applications where high heat stability is required. Colortherm® Red 520 is recommended for rubber plastic, coloring plastics or masterbatches. It has a shelf life of 10 years.
