In a short way, Masterbatch is a solid plastic additive used to color or impart other properties to plastics.
In a short way, Masterbatch is a solid plastic additive used to color or impart other properties to plastics.
A concentrated mixture obtained by the distribution of colours and additives into a polymer carrier by heat treatment and in-particularly a high shear mixing extruder is called masterbatch. The mixture is then cooled, cut and formed into granules via a pelletiser.
Masterbatch allows the processor to colour raw polymer economically during the plastics manufacturing process.
A color masterbatch, or color concentrate, is a granule used for coloring thermoplastics. It consists of one or more colorants and a polymer-specific carrier resin. The composition of a color masterbatch is called its recipe.
Masterbatches are highly concentrated with high \”let down ratios\”, one tonne of a natural polymer can fit into a 25 kg bag.
Masterbatches dilute nature, allowing higher accuracy in dosing of expensive components.
Masterbatches solid crystals are solvent free and tend to have a longer shelf life as the solvent in the polymer won’t evaporate. They generally contain 40-65 per cent additives, but the range can be altered from 15-80 per cent in a few additional cases.
Some of the most valuable benefits of masterbatch
When compared to raw pigments, masterbatch allows for higher accuracy of controlling the opacity or transparency of final, colored products.
Predetermined ratios of additive ingredients are included in masterbatch, which means there is a minimal chance of variance during the manufacturing process.
Masterbatching gives users better color consistency when working with large orders.
Melting processes are improved because binding agents in masterbatch are matched with polymers being used.
Unlike masterbatch, pigments can become airborne during processing, which allows them to contaminate adjacent manufacturing lines
