DuPont氟产品公司已使用其专有的超临界二氧化碳（scCO２）技术生产出第一批工业级Teflon氟聚物。由DuPont公司和美国北卡罗来纳－ChapelHill科学家在过去１０年联合开发出来的超临界工艺可取代以水为基础的传统聚合工艺。投资４０００万美元１．１kt／a设施已于２０００年末在 DuPont Fluorine Products has used its proprietary supercritical carbon dioxide (scCO2) technology to produce the first commercial grades of Teflon fluoropolymer. The supercritical process, developed jointly by DuPont and North Carolina-Chapel Hill scientists over the past decade, can replace the traditional water-based polymerization process. An investment of 40 million U.S. dollars in 1.1 kt / a facilities was in late 2000
