Masterbatch (MB) is a solid plastic additive that is used to colour plastics (colour masterbatch) or to impart additional qualities to plastics (additive masterbatch). Liquid colour is a type of liquid medication form. Masterbatch is a concentrated mixture of pigments and/or additives encapsulated in a carrier resin during a heat process, then cooled and chopped into granular shape. Masterbatches enable the processor to colour raw polymer in a cost-effective manner during the plastics process.

Buying a completely compounded substance or compounding from raw materials on site are the alternatives to employing masterbatches. When compared to pure pigments, masterbatches demand greater storage space and have longer lead times. Another downside is that the carrier and the additive are subjected to more heat exposure ("heat history"); this may be essential, for example, for marginally thermally stable pigments.

Palvi Masterbatches is a reputed Black masterbatches exporter in Colombia.

The use of masterbatches reduces the problems associated with additive or colourant clumping or insufficient dispersion. When it comes to masterbatch additives, their concentration is higher than in the final polymer, but the additives are well-distributed in the host resin. In some ways, their application is comparable to that of ferroalloys, which are used to add alloying elements to steels.

The masterbatches can be quite concentrated (in proportion to the desired composition), with high "let-down ratios"; for example, one 25 kg bag can be used for one tonne of natural polymer. Because masterbatches are relatively dilute (in compared to raw additives), they allow for more precision in dosing small amounts of pricey components. The compact form of the grains in solid masterbatches minimises dust concerns that would otherwise be associated with fine-grained solid additives. Because solid masterbatches are solvent-free, they have a longer shelf life because the solvent does not evaporate over time. The masterbatch typically comprises 40-65 percent of the addition, although in severe circumstances, the range can be as wide as 15-80 percent.

Palvi Masterbatches is one of the most distinguished Black  masterbatches suppliers in Colombia.

The typical masterbatch-to-base resin ratio is 1 to 5%. Several masterbatches (colours and additives) can be used concurrently. The carrier can also function as a plasticizer (which is typical in liquid masterbatches) or a processing aid.

Typically, the machines are fed pre-mixed granules of the host polymer and the masterbatch. The final mixing takes place in the screw and extrusion section of the machine. As a result, the masterbatch and base material can be separated, which can have detrimental repercussions. The masterbatch can also be added directly to the machine's screw, either as a free-flowing solid or by a peristaltic pump in the case of a liquid masterbatch. The use of liquid masterbatches enables for highly accurate dosing and rapid colour change between machine runs.

Advantages of Masterbatches:

Masterbatch has numerous advantages for the finished plastic products:


Masterbatch possess the ability of improving the production considering the volume. Furthermore, because of the increased film physical qualities, it has the capacity to downgauge.

Palvi Masterbatches is one of the leading Black masterbatches distributors in Colombia.

Cost Saving:

Because of the high CaCO3 specific heat of the component, masterbatch helps producers minimise material costs by requiring less energy to power the machine.

Physical Properties:

Masterbatch also helps the plastic in improving a variety of physical properties like;

  • Higher toughness
  • Flexural stiffness
  • Adhesion
  • Printability
