An examination of liquid and gaseous fluorochemicals for foam insulation. 2.

Author(s) : MURPHY J., COSTA J.

Summary

Previously, the authors reported the results of preliminary performance evaluations of several promising liquid HFC blowing agent candidates to replace R141b. The authors discuss the environmental, toxicological, flammability and performance characteristics of the liquid HFC blowing agent candidates. Environmental acceptability is the first criterion for a new blowing agent. A candidate must have a zero ozone depletion potential and a low global warming potential, and should be free from other environmental concerns. The toxicological properties of a blowing agent candidate must also be well understood. Performance of a new blowing agent is the ultimate criteria for acceptability. Data from laboratory foam evaluations involving both polyurethane and polyisocyanurate foams are presented. Other performance characteristics such as blowing agent solubility are discussed.
