Functional Carrier Fluids & Polymeric Dispersants

Our functional carrier fluids and polymeric dispersants offer a universal and sustainable approach to colourful plastics. An increased demand in consumer packaging, more focus on automotive lightweighting and improved manufacturing efficiency requirements are all contributing to growth in the liquid masterbatch market. Liquid colour masterbatch also offers benefits over solid colour masterbatch, such as:

  • being ideal for transparent and dilute shades
  • particular suitability for PET due to low addition rates
  • being less equipment intensive
  • compatibility with a broader range of polymers

Our Carrier Technology

Our bio-based carrier fluids offer tunable polarity and solubility to offer increased pigment loading and wetting. Benefits include:

  • polar functionality for improved pigment affinity
  • low volatility
  • low viscosity options for wetting inorganics
  • non-plasticising
  • miscible with mineral oil to allow dilution if necessary
  • higher viscosity options for additional shear in grinding organic pigments

Contact us to find out more about the carrier fluids we have available and the most suitable options for your application.

Polymeric Dispersants

Polymeric dispersants are added to pigment dispersions to improve the separation of particles, maximise loading, and to prevent settling and re-agglomeration. Polymeric dispersants offer a high affinity to pigments, multiple anchoring points, excellent adsorption and a large steric barrier. 

These benefits lead to faster dispersion, significant viscosity reduction, increased solids loading, superior stability and improved colour development
