Black Masterbatch
Black masterbatch is one of the most demanding masterbatch applications because carbon black is difficult to disperse. The final product requires deep color, stable tinting strength, clean surface appearance, and reliable performance in downstream processing.
A typical black masterbatch formulation contains carbon black, carrier resin, dispersing agents, and sometimes additional additives such as UV stabilizers or processing aids. The main challenge lies in breaking down carbon black agglomerates and distributing them evenly in the polymer matrix.
Nanjing Hundred Horse designs co-rotating parallel twin screw extrusion lines for black masterbatch production. The screw configuration, feeding arrangement, temperature profile, and pelletizing system can be adapted according to carbon black content, carrier resin, output requirement, and final application.
Important Process Targets
- Carbon black dispersion
- Color strength and consistency
- Uniform pellet quality
- Clean surface appearance of final plastic products
- Stable processing in film, pipe, cable, and injection applications
Typical Applications
- Garbage bags and packaging film
- Agricultural film and mulch film
- HDPE and PP pipes
- Cable sheathing
- Automotive plastic parts
- Injection molded products
- Sheets, profiles, and packaging materials
For black masterbatch producers, stable dispersion and repeatable production matter more than general mixing power. Hundred Horse extrusion lines are built to support continuous production with reliable compounding performance.
