Masterbatch (MB) is a solid additive for plastic used for coloring plastics (color masterbatch) or imparting other properties to plastics (additive masterbatch). A liquid dosage form is called liquid color. Masterbatch is a concentrated mixture of pigments and/or additives encapsulated during a heat process into a carrier resin which is then cooled and cut into a granular shape. Masterbatch allows the processor to color raw polymer economically during the plastics process.

At EJS, we produce segment twin screw barrel for masterbatch extruders. EJS is a professional manufacturer of Extruder Screw Elements for years, with customers of OEM machine builders as well as end users.
