It is highly recommended to check with suppliers before using any Omnicolor masterbatch for food contact applications. For polymer drying in excess of 225°F (107°C), add the colorant after the drying process, or alternatively contact Avient’s technical staff for availability of high-temperature grades. Low minimum order quantities are consistently available for both stock and non-stock colors—contact your local Avient representative for details.
