Carolina Color introduces UltraPET concentrate for tinted parts

Carolina Color Corp. (Salisbury, NC), a family-owned company specializing in full-service production capabilities and complete laboratories for color matching, testing and analytics, has introduced UltraPET, a new color concentrate specifically developed for use with PET resins.

UltraPET is based on G2, a patented technology from Carolina Color in which pigments and additives are highly loaded and well-dispersed in both large and small parts. The next-generation technology provides time, space and cost savings, said the company.

Matt Barr, CEO of Carolina Color stated, “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.”

Key attributes of Carolina Color Corp.’s new UltraPET color concentrates include a polymeric carrier that melts at temperatures 50% lower than traditional PET-based carriers, the elimination of migration and slippage issues, and compatibility with the base polymer. UltraPET’s mini beads have more pellet per gram and a larger surface area than competing products, resulting in a faster incorporation rate. These attributes help to achieve good color distribution, especially at lower use rates with tints.

There is no need to recrystallize the material, and drying may not be required at low use rates for tints. UltraPET features resistance to alcohols, is FDA compliant, and results in reduced housekeeping costs compared with liquid color.

Target applications for the UltraPET product line include cosmetic packaging, vitamin bottles, nutraceuticals, sample liquor bottles, spice jars and thermoformed sheets.
