MATERIAL BREAKTHROUGH: VERSAFLEX™ CE BLUE JEAN STAIN RESISTANT TPES FOR WHITE OR LIGHT-COLORED PHONE CASES Phone case brands have struggled to design white or light-colored cases that do not stain when in contact with blue jeans. Avient has formulated a new material that offers blue jean stain resistance similar to that of silicone*, yet with all the benefits of using a TPE: increased design freedom, an efficient supply chain leading to faster speed to market, and lower total part costs.
