The Over-molding (Versaflex® OM Series and VersollonTM which is a Urathane alloy) grades are specially formulated to bond to a variety of substrates.

Further, as a result of Avient's portfolio shift to a pure play specialty formulator, it has completed several acquisitions and divestitures which have resulted in a significant amount of intangible asset amortization.

Over the course of two decades the Company has transformed from a company focused on commodity products, to a specialty formulator of sustainable solutions. We believe our innovation pipeline remains robust, as we leverage our formulation expertise and sustainable solutions portfolio. Avient is a leading formulator of specialized and sustainable material solutions that transform customer challenges into opportunities, bringing new products to life for a better world.
