1990 Replacing CFCs

In 1990 DuPont started producing hydrochlorofluorocarbon and hydrofluorocarbon refrigerants under the brand name Suva® at Corpus Christi, Texas, and Maitland, Ontario, Canada. The first major market for Suva refrigerants was automobile air conditioners, the single biggest source of ozone-depleting CFCs. In 1993 the company advanced its CFC phaseout deadline to the end of 1994, one year ahead of the timetables established by the 1987 Montreal Protocol and by the 1990 Clean Air Act Amendments.Show more



By the end of 1994 DuPont was manufacturing eight different Suva refrigerants for use in car air conditioners, supermarket display cases, and home and restaurant refrigerators. In 1995 the company commercialized additional Suva products for home air conditioners and heat pumps. The market for non-CFC refrigerants increased in the late 1990s, and in 1999 DuPont expanded the production capacity of its Corpus Christi plant.
