DuPont Launches Capstone™ Products For Textile Use
Wilmington, Del.-based DuPont Chemical Solutions Enterprise has developed environmentally friendly
repellent and soil release finishes for textile use. The DuPont™ Capstone™ products, based on
short-chain chemistry involving six or fewer fluorinated carbons, meet the requirements of the US
Environmental Protection Agency's (EPA's) 2010/15 PFOA Stewardship Program. The EPA had asked
companies to commit to a 95-percent reduction by 2010 in emissions of perfluorootanoic acid (PFOA),
its chemical precursors and related higher homologue chemicals from their manufacturing plants, and
also to reduce levels of PFOA in products (See "
Initiates PFOA Stewardship Program," Feb. 7, 2006). DuPont used PFOA as a processing aid
in the production of its Teflon® polytetrafluoroethylene finish.
According to DuPont, Capstone products offer a step-change reduction in trace impurities of PFOA below the limit of detection without compromising fluorine efficiency. The products also meet Oeko-Tex® Standard 100 requirements and are bluesign® approved as a finish.
Capstone will be sold to mills under the Huntsman trade name Oleophobol®. Once a licensed mill meets performance specifications, its products will be marketed to the consumer as DuPont Teflon® fabric protector.
"Our customers that have converted to Capstone™ products in other market segments tell us that we have met their performance requirements," said Thomas H. Samples, surface protection solutions global business manager, DuPont Chemical Solutions Enterprise. "The introduction of Capstone products for textiles furthers the DuPont mission of sustainable growth - creating shareholder and societal value while reducing the environmental footprint along the value chains in which our customers operate."
