The study addresses the challenges of color matching in PCR for rigid packaging, offering options that can create global color consistency, quality, and circularity.   Moreover, coloring processes for dark recycled material can be challenging due to the need for high amounts of colorant to overcome the PCR base color.  Another key discovery from the study: If colorant must be added to the base material to achieve the desired color, the addition of color concentrate can be low (around 2%).

The colored grades feature BASF’s Ultrason® polyarylethersulfones (PAES) as high-quality base polymer combined with Avient’s Colorant Chromatics™ high-temperature color formulation expertise for color concentrates and pre-colored solutions.  The market requirements for colored, high-performance polymers are clear: you have to react quickly and also be able to supply various volumes of colored material,” says Anne Hippert, general manager, Colorant Chromatics at Avient. The colored grades will be formulated and sold by Avient as Colorant Chromatics™ made with Ultrason® by BASF.

Color is reflective light. Light travels into the color and reflects back to our eye the base and color of the sample we are viewing. Eventually, the color blocks enough light that it appears to be the correct color when viewed by eye.

CLEVELAND, – November 28, 2023 – Avient Corporation, a leading provider of specialized and sustainable material solutions and services, today announced it is adding new black colorants to its Renol™ Fiber Colorants portfolio. Satisfying all of these needs for deep black colorants in the textile industry has proven to be challenging over the past few years as certain color technologies could meet only one or two but not all requirements,” said Mauro Dallavalle, senior marketing manager, Color & Additives Fibers at Avient. The new deep black colorants are part of the Renol Fiber Colorants portfolio, a range of color concentrates specially formulated for dyeing synthetic yarns using the spin-dyeing (dope-dying) process.
