HFC-245FA Chemical compatibility with O-rings, rubbers, & plastics

HFC-245fa, also known as 1,1,1,3,3-pentafluoropropane, is a hydrofluorocarbon with the formula C3H3F5. It is a colorless, non-flammable liquid used primarily as a blowing agent in the production of polyurethane foam insulation. HFC-245fa is also employed as a refrigerant and a propellant in aerosol products. It is valued for its low global warming potential compared to older chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) compounds. Handling HFC-245fa requires caution as it can cause skin, eye, and respiratory irritation. Proper storage and handling procedures, including the use of personal protective equipment and good ventilation, are essential to prevent exposure. The compound's role in improving energy efficiency through insulation and its reduced environmental impact make it significant in modern industrial applications.
