1,1,1,3,3-Pentafluoropropane (HFC-245fa, R245fa) Applications.

1,1,1,3,3-Pentafluoropropane (HFC-245fa) is a hydrofluorocarbon used primarily for closed-cell spray foam insulation, as an alternative for dichlorofluoroethane (HCFC-141b) and trichlorofluoromethane (CFC-11).

HFC-245fa is also known as pentafluoropropane and by its chemical name 1,1,1,3,3,-pentafluoropropane. Unlike CFC and HCFC blowing agents formerly used for this purpose, it has no ozone depletion potential and is nearly non-toxic. Although it is intended to remain trapped within the foam insulation, it is practically non biodegradable with a lifetime of 7.2 years when it eventually does escape into the atmosphere. It does have a high global warming potential of 950 (950 times the global warming effect of CO2). HFC-245fa also can be used as refrigerant in special industry, replacing R-123 and R22.
