Many of today's household and commercial appliances require the use of polyurethane-based foam for its excellent insulating quality and structural rigidity. Department of Energy (DOE) standards and EPA Energy Star guidelines require energy efficiency ratings to be maintained. Polyurethane foam enables manufacturers of appliances to provide consumers with the features and performance they desire while satisfying these DOE and EPA requirements, economically and practically.
Fluorochemical blowing agents can be used to improve the thermal efficiency of PU insulation in refrigerators, freezers, and coolers. Forane® FBA 1233zd is a low GWP, non-flammable blowing agent well suited for use in appliance foams.
