Abstract
The paper gives results of a limited evaluation of the developmental hydrofluorocarbons (HFCs) 245ca and 236ea as blowing agents in urethane-based insulation. These materials were selected from screening tests of 37 C2, C3, and C4 isomers based on physical properties, atmospheric lifetime, flammability, estimated toxicity, difficulty of synthesis, suitability for dual use as a refrigerant, and other factors. Solubility of the two materials in typical foam components was tested, pour foaming trials were performed, and preliminary data were gathered regarding foam insulation performance.
