Colour masterbatches are pelletised colorants, comprised of high concentrations of pigments that have been pre-dispersed in a polymer. Additive masterbatches are the same, however rather than colour, they add extra properties. Examples include UV resistance, antimicrobial and antistatic additives. Custom compounds offer the same range of colour or additive in a pre compounded form.

4MAX® is the registered trade name for masterbatch and colour compounds produced by 4PLAS. We can offer either masterbatch or colour compounds, we have therefore developed an unbiased portfolio to suit your needs.
