ShareHCFCs and HFCs blowing agents for XPS insulating boards.
Author(s) : ALBOUY A., ROUX J. D., MOUTON D., WU J. H.
Summary
CFC-12 has long been the blowing agent of choice in XPS application due to its unique properties such as non-flammability, non-toxicity, low thermal conductivity and good processability. In developed countries, the rapid phase-out of CFC-12 was made possible thanks to the availability of HCFCs: HCFC-142b, pure or in blends with HCFC-22 or ethyl chloride, has now become the reference blowing agent for XPS insulating boards world-wide owing to its superior properties. This paper will discuss the current situation. A theoretical model will be used to simulate long term behaviour, especially thermal insulation. Using this theoretical model and available data, it enables the authors to have an insight of the foam performance that can be achieved by zero ozone depletion potential substitutes such as HFCs and CO2. HFC-134a appears to be the most promising one.
