DuPont has developed a new manufacturing process to remove greater than 97% of trace levels of perfluorooctanoic acid (PFOA), its homologues and direct precursors from its fluorotelomer products. This process meets key commitments of the EPA voluntary stewardship program for product content, three years ahead of schedule. The new LX platform products are expected to be drop-in replacements for current DuPont products. LX platform products do not require regulatory re-qualification and will continue to be listed on existing global regulatory clearances, including the U.S., Europe, Canada and Japan. The new products, based on existing DuPont Teflon, Zonyl and Foraperle chemistries, maintain a superior performance. The products will be used for surface protection in segments such as coatings, fluorosurfactants, paper packaging, leather and stone. More info: DuPont, Web: www.dupont.com.
