The Company acquired the Clariant Color business on July 1, 2020. André Schuhmacher, Chief Quality Manager “At L’Oréal, my job is to guarantee color consistency. Avient’s PCR Color Prediction Service helps me achieve this objective… The Redken launch would not have been possible without this service.”

It is widely used to manufacture films, bags, trays, bottles, and containers, and it has excellent overall properties such as impact and tensile strength, clarity, processability, colorability, and durability. Some key issues with PCR include degraded mechanical properties, inconsistent and gray coloration, unpleasant odors, or missing food contact approvals. A dedicated team is able to scientifically investigate details of the recycling process, understand the degradation and behavior of polymers, and develop the right additive and color masterbatches to increase the performance of PCRs and guarantee high recyclability of the final article.

HANDLING AND USAGE RATES Triple A is a dispersion which can be supplied individually or in combination with other ColorMatrix colorant and additive technologies. Universally compatible and easily combined with ColorMatrix color formulations. The additive has no impact on either color or clarity of containers and is easily combined with ColorMatrix color formulations.

THE IMPACT By replacing traditional sealing materials with non- halogenated OnFlex S HF TPE, Schneider-Electric NB (Strömfors) was able to offer its customers several significant benefits: • For flexibility in processing, OnFlex S HF TPEs can be supplied in either natural or pre-colored grades. Natural grades can be colored during processing with compatible products from Avient’s OnColor™ color concentrate line. • The non-halogenated solution has a density 0.4 g/cm3 less than a traditional halogenated material, and this density advantage makes it price competitive with the traditional solution. • High-flow properties of OnFlex S HF TPE allow the gaskets to be overmolded in multi-cavity tools (up to 12 cavities per tool). Additional advantages of these TPEs include: • Highly flame retardant without the inclusion of halogens • Low temperature flexibility • Excellent processability • Good abrasion resistance • Excellent colorability • Operating temperatures from -50° C to +100° C • All grades meet UL94-V0 at 1.5 mm • All grades pass IEC 60695-2-12 Glow Wire Flammability Index (GWFI) at 960°C

The PRT product line facilitates precise toner coloration through superior dispersion, ease of handling and dosing when compared to traditional powders. They are designed to be used separately but at the same time to control b* and a* color producing maximum L* color when used at very low dosing levels in the final product. This will generate a non-homogeneous dispersion, resulting in sub-standard coloration quality in the PET production process.

Further, the team developed a custom colorant that matched the automaker’s interior color specs, and then developed the final product so that the armrest could be molded in color.

Our Cesa™ Laser Marking Additives not only contain a laser marking additive but also deliver a part’s color and can include other additives such as those for scratch or UV resistance. The activation changes the molecular structure of these additives, causing a color change that provides the vivid contrast of laser marking. The mark can be white or dark in color.
