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. THE IMPACT • FLEXIBILITY through wide range of color options • PROTECTION of product through antimicrobial technology • SPEED to MARKET through supplier expertise • COST REDUCTION through simplified processing • CONSISTENT performance through all-inclusive, one step masterbatch Each Smartbatch solution is custom formulated to incorporate color, antimicrobial technology and UV stability in one material, simplifying them manufacturing process and delivering consistent performance
