DuPont™ Delrin® Renewable Attributed RA511CPE demonstrates breakthrough technology for sustainability



WILMINGTON, Del., December 13, 2021 /3BL Media/ - DuPont (NYSE:DD) Mobility & Materials is proud to announce that it has been named a 2021 R&D 100 Award winner in the Mechanical/Materials category. The R&D 100 Awards have been recognized as the most prestigious innovation awards program for the past 58 years, annually recognizing 100 winning products and technologies that will change industries and improve lives for years to come. This recognition continues DuPont’s impressive streak of new product innovation, having 31 finalists and ten R&D 100 winners in the last eight years. 

DuPont is being recognized for its Delrin® Renewable Attributed RA511CPE, the first commercial acetal homopolymer with a world-class environmental impact profile. Delrin® Renewable Attributed products demonstrate up to 75 percent reduction in Global Warming Potential (GWP) compared to fossil-based Delrin®. The innovative material comprises three renewable resources:

  • Municipal waste converted to steam as a heating source for the production process
  • Wind energy for renewable electricity to run the manufacturing facility
  • Bio-feedstock from secondary waste converted to bio-methanol for the Delrin® Renewable Attributed base polymer

“Sustainability is important to DuPont, to our customers, and to consumers who are increasingly concerned about environmental impacts,” said Valéry Rebizant, Global Product Technical Specialist, DuPont Mobility & Materials. “By adopting Delrin® Renewable Attributed, our customers can design parts that are lightweight, durable, reliable, and made with renewable materials. We are proud of this recognition of both our technical capability to produce sustainable polymers and our ongoing efforts to integrate innovative resources into our operations.”

The base polymer for Delrin® Renewable Attributed is produced from 100% certified bio-feedstock from waste in accordance with mass balance principles and is accredited through the International Sustainability and Carbon Certification (ISCC Plus) mass balance certification system. Delrin® Renewable Attributed is the stiffest unreinforced engineering resin available and used for applications that require a high degree of durability, reliability, and long service life.
