Refrigerant R-227ea is a colorless gas at normal temperature and pressure. As a clean, hexafluoropropylene environment-friendly, high affective and low toxic fire extinguishing agent, refrigerant R-227ea is ideal substitute for halon 1301,hexafluoropropane and has been accepted by NFPA in its 2001 new standard. R-227ea can also be used as refrigerant and medicine propellant.
