The term masterbatch or colour granule means Plastic additives in the form of Granules with a high content of colouring agents or additives. They are added to the Plastic (Raw polymer) to colour them or change the properties.

Due to the possibility of perfect dosing and easy product handling, masterbatches significantly increase process reliability in production processes, for example in extrusion and injection moulding.

Masterbatches are generally differentiated into three groups. Firstly, colour masterbatches to colour plastic products, secondly additive masterbatches that ensure the end products have specific properties, for example UV stabilisation, Flame retardant, Anti-static or antiblock and lastly combination masterbatches that contain both colouring agents and additives.
