The level of heavy metals in Colortherm iron oxide pigments are determined in the LANXESS laboratory. Customers then receive recommendations regarding the maximum pigment concentration in biodegradable plastic formulations with a low heavy-metal content. The masterbatch producer can then immediately develop formulations - and reliably comply with the relevant limits without the need for pigment screening.
