Color masterbatch is mainly composed of Resin, Color Pigments, dispersants, and additives. It is widely used in PP, PE, PS, ABS, Nylon, PC, PMMA, PET and other resins, producing colorful fibers, clothing, daily plastics, wires and cables, household appliances, agricultural films, auto accessories, health care equipment and other products.
Your benefits with CWT extruder for making color masterbatch
- Good price/performance ratio;
- Excellent dispersion due to optimum screw design and suitable elements selection;
- Higher Feeding for color pigment thanks to large, free screw volume (OD/ID could reach 1.7);
- With little influence on the sensitive pigment, the formula is safe;
- Out-standing product quality.
The basic machinery composition for Color masterbatch:
Raw material dealing system:
Gravimetric feeder/ premixer+ volumetric feeder
Twin Screw Extruder
Good dispersion of color pigment is very essential for the good final product during color masterbatch extrusion process. So screw design plays a very important role in color masterbatch extrusion process. The competence of the Cowell engineers with rich working experience and enables the extruder to have an optimum screw design with structured screw elements and barrel.
