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