   “The proposed replacement for CFC-11, a chlorofluorocarbon used to make plastic foam and in central air-conditioning systems, is a compound called HCFC-22. This is a chlorofluorocarbon already in use in home air-conditioners, but it is more expensive than CFC-11 and its potential applications are limited by its inferior characteristics.”

   “The Renew is also free of polyvinyl chloride, asbestos, chlorofluorocarbons and halons.”
