FURTHER DEVELOPMENT OF LOW GWP FOAM EXPANSION AGENT WITH IMPROVED INSULATING PERFORMANCE VS. COMMERCIALLY AVAILABLE OPTIONS TODAY

摘要

DuPont Fluorochemicals has developed a novel "Fourth-Generation" foam expansion agent, FEA-1100. It has zero ODP (Chlorine-free) and low GWP (GWP<10). It is also non-flammable and a stable liquid with a boiling point of 33 °C. We report here further application studies on FEA-1100, including material compatibility and the performance of FEA-1100 with the major types of polyols employed for the manufacture of polyurethane foams. The results indicate that FEA-1100 can be employed in a broad range of foam applications to provide superior insulation performance compared to hydrofluorocarbons (HFCs) and hydrocarbons. Performance and materials compatibility test results indicate that FEA-1100 may be employed as a "drop-in" replacement for other liquid foam expansion agents (FEAs), providing improved insulation performance with low conversion costs.
