Plastic Pigments & Masterbatch: Getting Consistent Colour Every Batch
Colour is often the first thing a customer notices - here's how the right pigment or masterbatch keeps it consistent, batch after batch.
What Are Pigments and Masterbatch?
Pigments are colorant materials that give plastics, coatings and inks their colour, while masterbatch is a concentrated pigment dispersion carried in a polymer base, designed for easy and consistent dosing during processing. Siya Polymer & Speciality Chemicals supplies organic and inorganic pigments, pigment powders, pigment pastes and pre-dispersed masterbatch for plastics, packaging, automotive and industrial applications.
Pigment Powder vs Masterbatch - Which to Choose?
Pigment powder offers flexibility for custom colour matching but requires careful dispersion control during processing. Masterbatch offers superior consistency, easier handling and better dispersion since the pigment is already uniformly distributed in a carrier resin - making it the preferred choice for high-volume production where colour repeatability is critical.
Key Properties to Look For
- High tinting strength for cost-efficient dosing
- Light fastness to prevent fading under UV exposure
- Heat stability to survive processing temperatures without degrading
- Chemical resistance for demanding end-use environments
- Excellent, consistent dispersion for uniform colour across every batch
Applications
Pigments and masterbatch are used across injection moulding, extrusion, packaging films, automotive components, consumer goods and industrial coatings wherever consistent, durable colour is required.
