Heptafluoropropane (HFC-227ea):
1. It is a colorless,nearly odorless, insulation gas at room temperature and normal pressure.
2. Its density is six times that of air.
3. It is a colorless,nontoxic,nonflammable and transparent liquid under the pressure created by itself.
4. It has excellent thermal and chemical stabilities.
5. As a clean,environment-friendly,high effective and low toxic fire-extinguishing agent, it is an ideal substitute for halon 1301, and has been listed on NFPA2001 standard fire-extinguishing agent by the US national fire proof association.
6. It can also be used as refrigerant and medicine propellant.
