After developing a deep understanding of the customer’s needs, Avient’s team quickly went to work to formulate a custom OnColor™ color and then added Cesa™ WithStand™ antimicrobial technology to make a single Smartbatch™ masterbatch that passed all of the product’s challenging requirements. This combined additive and color technology not only solved the color harmony challenge across all polymers used in the various components of the personal care device, but also accelerated testing because the Cesa WithStand antimicrobial material used had been pre-tested for polymeric integrity. © 2022, All Rights Reserved Avient Corporation, 33587 Walker Road, Avon Lake, Ohio USA 44012 ANTIMICROBIAL TECHNOLOGY, CUSTOM COLORS AND PERFORMANCE ADDITIVES IN ONE MASTERBATCH.
