Masterbatch

Masterbatch is a concentrated mixture of pigments, additives, or other ingredients that are added to polymer resins to impart specific properties to the final product. The masterbatch is usually made into small pellets or granules and is then added to the polymer during the manufacturing process. The purpose of using a masterbatch is to improve the final product's color consistency, resistance to environmental stress, and overall performance. Masterbatches are commonly used in the production of various plastic products such as films, fibers, and injection-molded parts.
