Therefore, they tend to have a longer shelf life as the solvent will not evaporate over time. Solid masterbatches are also solvent-free. The compact nature of the grains of solid masterbatches eliminates problems with dust, otherwise inherent for fine-grained solid additives. The relatively dilute nature of masterbatches, compared to the raw additives, allows higher accuracy in dosing small amounts of expensive components. The masterbatches can be highly concentrated (compared to the target composition), with high "let-down ratios" for example, one 25 kg bag can be used for a ton of natural polymer. ![]() The use of masterbatches allows the factory to keep stock of fewer grades of the polymer, and to buy cheaper natural polymer in bulk. In a way, their use is similar to the uses of ferroalloys for adding alloying elements to steels. The concentration of the additive in the masterbatch is much higher than in the end-use polymer, but the additive is already properly dispersed in the host resin. Īs masterbatches are already premixed compositions, their use alleviates the issues with insufficient dispersion or clumping of the additive or colorant. Another disadvantage is additional exposure of heat ("heat history") to both the carrier and the additive this may be important, such as for marginally thermally stable pigments. In comparison with pure pigments, masterbatches require more storage space and their lead times are longer. color variability of the product), or compounding from raw materials on site (which is prone to issues with achieving full dispersion of the colorants and additives, and prone to preparing more material than what is used for the production run). The alternatives to using masterbatches are buying a fully compounded material (which may be more expensive and less open to e.g. Masterbatch allows the processor to color raw polymer economically. Masterbatch is a concentrated mixture of pigments and/or additives which is manufactured by encapsulation during a heat process or twin screw extrusion into a carrier matrix resin, which is then cooled and further cut into a granular shape.
