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.
