Tailor made HFC-245fa foam for appliance applications

摘要

Eight years ago, the use of CFC-11 in rigid foam applications was terminated in the U.S. due to environmental concerns arising from its ozone depletion potential. Since that time, rigid foam manufacturers have used the second-generation blowing agents with more and more confidence. In general, the predominant blowing agent for the U.S. market over this period has been HCFC-141b.
