HFC-245fa, or 1,1,1,3,3-pentafluoropropane, is a third-generation alternative blowing agent designed to replace chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) in various applications. It is primarily utilized as a blowing agent for rigid polyurethane (PU) foam, which is extensively used in refrigerators, cold storage, and building boards. Additionally, HFC-245fa serves as a refrigerant, effectively replacing R-123 and R-22 refrigerants in central air conditioning systems (chillers). Quality Index: Purity: 99.8% Moisture (% w/w): 0.0020 Acidity (as HCl, ppm w/w): 0.0001 Evaporation Residue: 0.01 Color: Colorless liquid HFC-245fa's high purity and low moisture content make it suitable for a wide range of industrial applications, ensuring optimal performance and reliability.
