Masterbatch
Masterbatch is a solid or liquid additive for plastic used for coloring plastics (color masterbatch) or imparting other properties to plastics (additive masterbatch). Masterbatch is 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. Masterbatch allows the processor to colour raw polymer economically during the plastics manufacturing process.
Applications of additive masterbatches
Additive masterbatches modify various properties of the base plastic:[1]
- ultraviolet light resistance
- flame retardant
- anti-fouling
- anti-static
- lubrication
- anti-slip
- corrosion inhibitors for metals packaged in plastic
- anti-microbials
- anti-oxidants
- extrusion aids
- phosphorescence
