Color Masterbatch Preparation (High-dispersion Pigments)

A compounding extruder, also known as a mixing extruder or twin screw compounding machine, is specialized equipment designed for plastic compounding, polymer modification, additive blending, and masterbatch production. Using high-efficiency co-rotating twin screws, the compounding extruder offers excellent mixing, dispersing, shearing, and homogenizing performance. It is widely used in manufacturing engineering plastics, color masterbatch, filler masterbatch, biodegradable materials, elastomers, and functional additives.

The compounding extruder combines precision temperature control, modular screw elements, multi-zone mixing, and various feeding systems to achieve optimal dispersion and stable pellet quality. It is ideal for applications requiring high consistency, precise formulation control, and continuous production, making it a preferred solution for materials R&D and large-scale compounding factories.

Applications of the Compounding Extruder

Polymer Compounding: PP, PE, ABS, PA, PC, PET, PBT, TPU, TPE.

Masterbatch Production: color, filler, carbon black, and additive masterbatch.

Engineering Plastics Modification: glass-filled, flame-retardant, impact-modified systems.

Biodegradable Materials: PLA, PBAT, PHA, starch-blended compounds.

Chemical & Additive Blending: stabilizers, compatibilizers, nano-fillers.

Recycling & Reprocessing: mixed plastics and production waste.
