Forane® 134a blowing agent
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.
As third generation hydrofluorocarbons, Forane® 365mfc/227ea blends (87/13 and 93/7) are the ideal replacements for R-141b for rigid foam blowing agent needs. Forane® 365mfc/227ea blends have zero ozone depletion potential and boiling point similar to HCFC 141b, thus they can be handled as a true liquid at room temperature. While the straight Forane® 365mfc has a flash point, Arkema offers two different blends that have no flash point and are not subject to flammable liquid regulation. Available in Europe.

Forane® FBA 1233zd foam blowing agent
Forane® FBA 1233zd is a high performance, low global warming potential (GWP) liquid blowing agent that is SNAP approved for most polyurethane (PU) applications, including residential appliance, commercial refrigeration, construction panels and doors, as well as spray foam. Forane® FBA 1233zd is non-flammable, liquid blowing agent.
Transcend® additive technology offers a unique approach to improving next-generation foam technologies; it goes beyond a single performance enhancement. Transcend® technology, based on trans-1,2-dichloroethylene (Trans-1,2-DCE), can be added to HFC and HFO foam formulations to create unique foam products. Transcend® technology delivers improved compatibility of blowing agents and polyols as well as reduced viscosity, thus improving the flow characteristics of many foam formulations.
