OUR VISION At Avient, we create specialized and sustainable material solutions that transform customer challenges into opportunities, bringing new products to life for a better world. We create specialized and sustainable material solutions that transform customer challenges into opportunities, bringing new products to life for a better world. Our customers value the breadth of our solutions as we can tap into a broad array of raw materials to solve their specific needs.

This region of the world maintains a high sensitivity to preserving nature and the environment, and the producer’s desire to look for alternative material solutions not yet required by law follows this cultural tendency. THE SOLUTION The Schneider-Electric NB (Strömfors) design staff turned to Avient for help in selecting the right material. Natural grades can be colored during processing with compatible products from Avient’s OnColor™ color concentrate line. • The non-halogenated solution has a density 0.4 g/cm3 less than a traditional halogenated material, and this density advantage makes it price competitive with the traditional solution. • High-flow properties of OnFlex S HF TPE allow the gaskets to be overmolded in multi-cavity tools (up to 12 cavities per tool).
