DuPont Performance Polymers THE INDUSTRY’S BROADEST PORTFOLIO OF RENEWABLY SOURCED MATERIALS

DuPont™ Renewably Sourced™ Materials*

UNIQUE MATERIAL SOLUTIONS MEET TODAY’S SUSTAINABILITY CHALLENGEBy tapping innovative technology and strategic partnerships, DuPont has created novel methods of manufacturing high-performance materials from renewable resources. This new generation of materials, derived from biomass instead of petroleum, reduces the environmental footprint without compromising performance. The versatile offering includes several families of PTT polyester, thermoplastic elastomer, and nylon products.

The DuPont™ Renewably Sourced™ (RS) Lineup

Sorona® EP thermoplastic polymers

Sorona® EP thermoplastic polymers are PTT polyesters made with a renewably sourced propanediol (PDO) currently derived from corn sugar. Development work is also focused on utilizing non-food renewable sources. Sorona® EP thermoplastic polymer starts with the basic Sorona® polymer (fiber) chemistry and then uses a proprietary formulation technology to create high-performance engineering polymer resins.

Performance benefits vs. PBT

■ Stronger and stiffer

■ Better surface appearance

■ Lower shrinkage and warpage

Processing advantages

■ Can be molded using conventional injection molding machines

■ Drying requirements like other polyesters

■ Cycle times similar to PBT

Key applications

■ Electrical/electronics

■ Automotive components

■ Industrial and consumer products

■ Appliance parts

■ Power tool applications

■ Furniture

■ Food contact compliant grades available

DuPont™ Sorona® EP thermoplastic polymers are PTT polyesters with 20% to 37% renewably sourced materials (by weight) and properties similar to high-performance PBT polyester.
