Additive Range for PVC consist of a concentrated mixture of pigments and/or encapsulated additives manufactured by heating a carrier resin, which is then cooled and cut into granules. The masterbatch thus allows the processor to color the natural polymer economically in the plastics processing process.
We have colored, black, combi or additive PVC masterbatches (with solid or liquid carriers), which aim to color or give other properties to plastics – colored or additive masterbatches.
The masterbatch carrier must be identical/compatible with the polymer. For example, EVA or LDPE is a carrier compatible with polyolefins and nylon, just as polystyrene is used as a carrier for ABS, SAN and sometimes polycarbonates.
In this sense, when the masterbatch carrier is incompatible with the raw material, changes may occur in the properties of the processed material. The processor must specify the characteristics of the raw material. The percentage of use of masterbatches in relation to the raw material is between 1 and 5%. Masterbatches, color and additive(s) or combined.
Masterbatches are compatible with most processes, with the exception of rotational molding, plastisol and other liquid resin systems.
Our partner, Astropol, can create various additive masterbatch product samples including:
