Masterbatch Types Explained: White, Black, Colour & Additive Masterbatch
Masterbatch isn't just about colour - four broad categories cover everything from UV protection to opacity to full custom colour matching.
What Is Masterbatch?
Masterbatch is a concentrated mixture of pigment or additive encapsulated in a carrier resin, pelletized for easy dosing into a base polymer during processing. It lets manufacturers add colour or function without handling raw pigment powder, which is messier and harder to dose accurately.
White Masterbatch
White masterbatch, typically based on titanium dioxide, is used to achieve opacity and brightness in products like packaging film, pipes and containers - and is also the base many colour masterbatches build on for lighter shades.
Black Masterbatch
Black masterbatch, usually carbon-black based, is one of the most widely used types across industries, valued for opacity, UV protection and consistent deep colour in products ranging from pipes to automotive parts to packaging.
Colour & Additive Masterbatch
Colour masterbatch delivers custom Pantone or RAL-matched shades for branding consistency, while additive masterbatch delivers a functional benefit - UV stability, antistatic performance, flame retardancy or slip properties - without colour being the primary purpose.
Siya Polymer supplies white, black, custom colour and additive masterbatch for PP, PE and engineering plastic applications.
