DuPont™ Sorona® EP thermoplastic polymers contain between 20% and 37% renewably sourced material (by weight) derived from corn. The new material exhibits performance and molding characteristics similar to high-performance PBT (polybutylene terephthalate).
In addition to good strength and stiffness, early tests indicate improved surface appearance, lower warpage, and good dimensional stability, making it very attractive in a range of uses for automotive parts and components, electrical and electronics systems as well as industrial and consumer products.
||DuPont™ Sorona® EP thermoplastic polymers are derived from corn with DuPont Tate & Lyle Susterra™ renewably sourced™ propanediol as a key intermediate. The exact percentage of renewably sourced content for each commercial product is available on the renewable.dupont.com web site.
Sorona® EP thermoplastic polymer starts with the same basic polymer chemistry as Sorona® polymer used for fibers but through proprietary formulation technology, further enhancements are added to create high-performance resins suitable for engineering plastics applications.
