Pentafluoropropane
1,1,1,3,3-Pentafluoropropane (HFC-245fa) is a hydrofluorocarbon is a colorless gas used primarily for closed-cell spray foam insulation. HFC-245fa is also known as pentafluoropropane and by its chemical name 1,1,1,3,3-pentafluoropropane. Environmental Effects 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 ). Honeywell refers to this as "acceptable" in their literature, but they don't include the actual number. Economics One of the disadvantages of R-245fa is its cost. In 2000, R-141b cost one US dollar per pound, whereas R-245fa cost $2.50 to $4.00 per pound. As of 2007, and prior to Sinochem's production it was alread ...
