Masterbatch Extruder
A masterbatch extruder, also called a color masterbatch machine or masterbatch production line, is specialized equipment designed for producing color masterbatch, filler masterbatch, and additive masterbatch used in the plastics industry. Equipped with a high-efficiency twin screw extruder, the masterbatch extruder ensures excellent dispersion of pigments and additives, achieving stable color performance and uniform pellet quality. It is widely used in film extrusion, injection molding, blow molding, pipe production, and engineering plastics compounding.
This type of extruder integrates precise heating control, adjustable screw configurations, high-shear mixing, and advanced pelletizing systems to meet various masterbatch formulations. It supports pigments, carbon black, calcium carbonate, flame retardants, UV stabilizers, and functional additives. The masterbatch extruder is ideal for manufacturers requiring high-color strength, consistent dispersion, and repeatable production results.
Applications of the Masterbatch Extruder
Color Masterbatch: PE/PP/ABS/PS color concentrate, black masterbatch, white masterbatch.
Filler Masterbatch: CaCO₃ filler, talc, barium sulfate, and mineral-filled compounds.
Additive Masterbatch: anti-UV, anti-static, flame retardant, antioxidant, slip agents.
Engineering Plastics Modification: PA, PC, PBT, PET masterbatch compounding.
Functional Polymers: biodegradable materials, heat-resistant formulations.
