Masterbatch Extrusion: Guide to Plastic Manufacturing and Recycling

Masterbatch adds colour and properties to plastics. Here is how extrusion produces it and how it supports recycling.

Masterbatch is a concentrated mixture of pigments or additives encapsulated in a carrier resin, used to colour or modify plastics during processing.

The Extrusion Process

Raw materials are dosed into a twin-screw extruder, melted and mixed, then pushed through a die, cooled and cut into pellets.

Role in Recycling

Additive masterbatches can restore properties of recycled plastics, improving strength, UV resistance and appearance.
