CFCs and the Environment: Further Observations

Richard Llewellyn Powell; J. Hugo Steven

The introduction of the chlorofluorocarbon (CFC) fluids in the early thirties marked the inception of the organofluorocarbon industry. Both in terms of tonnage produced and product value, they have dominated the industry and provided feedstocks for the development of other products, such as fluoropolymers (see Chapter 6).
