Carolina Color Corporation introduced a new color concentrate, UltraPET, specifically for use with PET resins.

This UltraPET color concentrate represents continued growth in color innovation based on G2, a patented technology from Carolina Color Corporation in which pigments and additives are highly loaded, well-dispersed, and can effectively distribute in both large and small parts. The unique qualities of this next-generation technology result in the proven benefits of time, space, and cost savings, according to the company.

"We are thrilled to introduce this product line to meet the PET color needs for the plastics molding industry. Innovation is a core competency of Carolina Color and this type of investment is necessary for the company and the industry to grow," says Matt Barr, CEO of Carolina Color.

Key attributes of Carolina Color Corporation's new UltraPET color concentrate include:

  • Polymeric carrier that is low melting and has excellent compatibility with the base polymer. The polymeric carrier will not migrate and cause screw slippage issues
  • Mini beads that will have more pellets per gram and larger surface area. These attributes will help with good color distribution especially at lower use rates with tints
  • Melts at 50% lower temperature than traditional PET based carriers
  • Improved rheology and larger surface area of the mini beads leading to a faster incorporation rate
  • Compatibility with PET bottle resins
  • High loading capability
  • No need to recrystallize
  • Drying may not be required at low use rates for tints
  • Resistance to alcohols
  • Reduced housekeeping cost compared to liquid color
  • FDA compliant

Targeted applications for this newUltraPET product line include cosmetic packaging, vitamin bottles, nutraceuticals, sample liquor bottles, spice jars, thermoformed sheets, and more.
