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. It exhibits all the same mechanical properties and performance advantages as traditional fossil-based Delrin. Naturally resilient and self-lubricating, Delrin Renewable Attributed is ideal for gears, conveyor belts (material handling), consumer electronics, smart and wearable drug delivery devices, safety restraint systems in automotive, and consumer applications. Delrin Renewable Attributed can support our customers in meeting with performance and sustainability goals.
