Renewable Bio Based Polymers

Raising the Performance Bar for Bio Based Polymers

DuPont is helping to reduce dependence on fossil fuels with the industry’s largest portfolio of renewably-sourced biopolymers

DuPont has invested extensive scientific research and development to create next-generation bio based polymers to help reduce the use of fossil fuels without reducing performance.

For polymers the terms “Renewably-sourced” and ”bio-based” mean the same thing. They refer to a material that contains carbon originating from a renewable plant source.  Materials are defined as renewably sourced when they contain a minimum of 20% by weight of plant sourced ingredients verified by 14C dating (ASTM definition).

Benefits of specifying biopolymers, made from a renewable plant source, or biomass, can include LEED certification points, and reduction in use of fossil fuels. At the same time, DuPont biopolymers provide durability and other qualities that enable application-critical performance in demanding applications.



  • ProShield® Coveralls

  • Sorona® EP Thermoplastic Polymer

    DuPont™ Sorona® EP Thermoplastic Polymer contains 37% plant-derived renewable material by weight for a reduced polymer environmental footprint. And Sorona® has a desirable set of performance characteristics as well, including improved surface performance, strength, and dimensional stability.


  • Sorona® for Casual Wear

    DuPont™ Sorona® enhances casual wear fabrics when blended with both man-made fibers like polyester and natural textiles like cotton, wool, and linen.

  • Carpet Design and Sorona®

    Renewably Sourced™ DuPont™ Sorona® is opening up new possibilities for carpet design. Durable and color-fast, with permanent stain resistance built right into the fiber, the Sorona® carpet design option is also the right choice in terms of performance.

  • Triexta, Generic in Name Only

    Specific performance benefits, including stain resistance, are so unique to DuPont™ Sorona®, the U.S. FTC gave the generic name triexta to homo fibers made from PTT, the Sorona® renewably sourced polymer.

  • Sorona® Performance in Apparel

    DuPont™ Sorona® delivers innovative performance to all types of textile fibers for apparel. A renewably sourced fiber, Sorona® provides exceptional softness, comfort stretch, superior tensile strength, lower dyeing temperatures and more. No other fiber combines so many performance and environmental benefits.

  • Sorona® and Bio-Based Product Labels

    The USDA BioPreferred Certification of DuPont™ Sorona® means manufacturers can offer innovative products that customers can readily identify. Innovative products help reduce the use of fossil fuels and help reduce emissions.

  • Sustainable Plastics

    Renewably sourced DuPont biopolymers are used in sustainable plastics that can replace oil-based materials and reduce dependence on fossil fuels.

  • Vehicle Design Options Multiplied
