The report presents the findings of a select international committee of experts from industry and academia on the subject of chemical substitutes for fully halogenated chlorofluorocarbons (CFCs). The committee, over the course of two meetings, reviewed and discussed data and information on chemical alternatives for fully halogenated CFCs now in use. The committee acknowledged that, while there are many other possible chemical replacements, there is a dearth of information on these compounds with regard to property data, toxicity, and performance in end-use applications.
