Functions performed by DuPont polymer modifiers

Impact Resistance/Toughness — Available levels of toughening range from general-purpose, to low-temperature, to supertough, with DuPont nonreactive and reactive modifiers to match. >Learn more ...

Coupling/Adhesion — Fillers such as glass fiber, minerals or flame retardants can increase the service level and value-in-use of plastic resins. Coupling agents promote adhesion and aid in filler wetting and dispersion. >Learn more ...

Compatibilizing — The general principle of compatibilization is to reduce interfacial energy between two polymers in order to improve their performance when combined. >Learn more ...

Plasticizing/Flexibility — Make stiff plastics (such as PVC) more pliable and longer lasting by adding solids phase flexibilizers instead of liquid plasticizers. >Learn more ...

Masterbatch Carrier Resins — Colors (and other additives) are often managed using "master batches" or "carrier resins" that can be incorporated into other plastics. Because of their excellent thermal stability, broadly compatible Elvaloy® AC resins can be used as carrier resins in conventional and high-temperature systems. >Learn more ...
