Addivant Polymer Modifiers are the industry’s leading compatibilizers, which are also known as functionalized polymers, coupling agents or impact modifiers. They are used in applications such as PVC calendaring, PVC profiles, engineering thermoplastics compounding, thermoplastic elastomers, epoxy adhesives and coatings, masterbatches, polyolefin compounding, filler coupling, solvent adhesives, and alloy compatibilization.
