Just a few months ago, we completed the acquisition of the Clariant Masterbatch business, the largest acquisition in the 20-year history of our company. It’s in this spirit that we joined legacy PolyOne and the Clariant Masterbatch business, two complementary businesses, and formed a new one that we’ve named Avient. Such is the case with the Clariant Masterbatch acquisition, where strong free cash flow will allow us to de-lever quickly. 19 AVIENT IS MODESTLY LEVERED 1.

Finding suppliers of fluoropolymer color and additive masterbatches able to meet its standards has not always been easy. That inconsistency led to masterbatches that included lumps and lot-to-lot color differences. With RoHS and REACH documentation on all masterbatch orders, international customers were an option once again.

Quality Masterbatches for Spun-Dyed PET and PA The masterbatches are offered in pellet form and developed for optimal fiber coloration in the POY, FDY, DTY, ATY and BCF manufacturing processes. The color can be combined with additives for a single masterbatch solution that provides coloration and enhances the properties of spun-dyed fibers.

Masterbatch approach eliminates added cost, chemical volatility of painting The new material, which could be produced in a metallic-effect masterbatch, would allow the supplier to replace the time-consuming painting process. The switch to masterbatch technology was made without a large capital investment.
