- Other Notes
- U.S. production stopped December 31, 1995. Chlorofluorocarbon (CFC) products such as R-500 are no longer manufactured but are still used in a variety of systems, and service refrigerant is sometimes still available in reclaimed form in some developed countries including the United States. In countries operating under "Article" provisions of the Montreal protocol agreement, CFCs in virgin form are still available, although these countries are now beginning to implement CFC phase-outs. Consider R-402A, R-402B, R-408A, R-404A, R-507
