Polymers such as EVA or LDPE can be used as carriers for polyolefins and nylon, while polystyrene can be used for ABS, SAN, and sometimes polycarbonates.
[2] Processing machines are usually fed with premixed granules of the host polymer and the masterbatch, where the final mixing takes place in the screw and extrusion parts of the processor.
Granule processing is sometimes prone to causing adverse effects, such as the separation of the masterbatch and the base material in the hopper.
[2] The additives in a masterbatch are chosen to impart desired physical property changes to a final plastic product.
[8] Depending on the needs of the output product, manufacturers mix primary plastic with additives in a certain amount.
