HFC-227ea
Heptafluoropropane (HFC-227ea) is a colorless, almost tasteless,
non-conductive gas at room temperature and pressure, its density is
about 6 times that of the air; It is a colorless and transparent
liquid under its own pressure, non-combustible, non-corrosive, with
good thermal and chemical stability.
Because of its high fire extinguishing efficiency, low toxicity,
non-destructive to the ozone layer, and non-polluting to the use
site, it is considered an ideal substitute for Halon 1301 and has
been included in the NFPA 2001 standard for fire extinguishing
supplies by the National Fire Protection Association. In addition,
heptafluoropropane is also used as a refrigerant and medical
spraying agent.
