Color masterbatch (MB) is a solid additive for plastic used for coloring plastics. This masterbatch is also a concentrated mixture of pigments and (or) additives encapsulated during a heat process into a carrier resin which is then cooled and cut into a granular shape.
Color masterbatch processing
Masterbatch processing is the extreme situation for processing aids, where very high loadings of fillers or pigments must be efficiently incorporated with a resin carrier. In particular, masterbatch compounders are challenged when integrating high percentages of titanium dioxide, carbon black, phthalocyanine blue pigment, or other difficult-to-disperse fillers.
Processing of color masterbatch is as below:
- Weighing
- Mixing
- Twin-screw extruding
- Cutting and cooling
- Sieving
- Bagging
Advantages of using color masterbatch in plastic manufacturing
This material brings many advantages for the final plastic products
- Productivity: increase volumetric output (as a result of thermal conductivity & volumetric expansion to temperature). In addition, it has ability to downgauge due to higher film physical properties.
- Total save cost: with the large percentage of CaCO3 powder in component, color masterbatch helps manufacturers reduce material cost by using less energy to run the machine due to higher CaCO3 specific heat.
- Improving physical properties: higher toughness, flexural stiffness, adhesion, printability.
Areas using color masterbatch
