Polymer Additives Improve Functionality and Performance
DuPont polymer additives for plastic compounding include performance-tailored tougheners, coupling agents, flexibilizers and mixed plastics compatibilizers.
DuPont focuses on global supply of polymer additives and modifiers that play specialized performance roles in plastics manufacturing. DuPont polymer additives contribute to more efficient compounding, higher-value plastics from existing production lines, easier and more consistent downstream processing and easier recycling.
DuPont’s specialized modifier resins include copolymers, terpolymers, ionomers, and grafted polyolefins. DuPont employs advanced polymer chemistry to create modifier resins with precision functionality in compounded plastics.
DuPont™ Surlyn® for polymer modification is used as a processing aid and compatibilizer in PET. It also is used as a nylon toughener in automotive parts.
