Are you familiar with the common processes for producing color masterbatches？

Color masterbatch production involves strict requirements and utilizes both dry and wet processes, with ongoing advancements in technology.

Wet Process:

The wet process includes grinding, phase transformation, water washing, drying, and pelletization. Technical tests during pigment grinding assess parameters like slurry fineness, dispersibility, and solid content. Four methods are commonly employed: ink method, washing method, kneading method, and metal soap method.

Ink Method:

Ingredients → Mixing → Grinding → Mixing and extruder Compounding → Extrusion and Pelletization → color masterbatch

Washing Method:

Pigment + Water + Dispersant → Grinding → Evaporation, Concentration, Drying → Mixing and extruder Compounding → Extrusion and Pelletization → color masterbatch

Kneading Method:

Pigment + Carrier Resin → Kneading → Extrusion and Pelletization → color masterbatch

Metal Soap Method:

Pigment + Dispersant → Grinding → Mixing and extruder Compounding → Extrusion and Pelletization → color masterbatch

Dry Process:

For high-grade color masterbatches, pre-dispersed pigments are prepared and dry processes are employed for pelletization. Production conditions vary based on product requirements. Commonly, a high-speed plastic mixer machine and twin screw extruder are used. Some companies grind carrier resin into powder to enhance pigment dispersion. Single-screw or twin-screw mixing machines are also used for high-quality color masterbatch production. Color matching and measurement technologies, including high-performance spectrophotometers, are widely adopted. color masterbatches cater to plastics, rubber, and synthetic fibers, evolving from universal to specialized applications. The industry is witnessing trends of diversification, specialization, functionality, high pigment content, and advanced technology.
