ColorMatrix™ Joule™ Reheat Additive for PET

Cut energy usage and enhance aesthetics

Sustainability remains high on the packaging industry’s agenda and eco-friendly solutions that don't add complexity and cost are winners amongst brands, converters and resin suppliers. ColorMatrix Joule™ technology hits the mark. These innovative infrared-absorbing additives are added to PET resin at the reactor stage to provide an eco boost during the blowing of container preforms. But the benefits don’t stop there. Aesthetic quality at point of sale and further energy gains downstream during multiple heat processes are all part of the package. Choose from two base formulations to give your PET products improved performance without compromising on sustainability. 


  • Advanced infrared absorption capability
  • Inherent toning capability
  • Improved recyclability for blended resins
  • Helps maintain visual clarity through multi-trip recycling
