Product overview

Forane® 141b is a liquid blowing agent ideal for spray foam applications. Since it is a liquid at atmospheric conditions and has low vapor thermal conductivity, which allow the production of polyurethane foam with excellent physical properties. The low vapor thermal conductivity of Forane® 141b makes it ideal for the appliance market. Forane® 141b is an ideal blowing agent for polyurethane core metal-faced panels used for construction.  R-141b is an HCFC and, as an ozone-depleting substance, is subject to phase out according to the Montreal Protocol international treaty and the Clean Air Act in the United States; it has been phased out in the United States for use in foam.
