R227ea, heptafluoropropane (HFC-227ea, FM200) is a colorless, odorless, low-toxicity, good insulation, and no secondary pollution gas. It has zero depletion potential (ODP) on the atmospheric ozone layer. As a fire extinguishing agent, it is currently the most ideal substitute for halon 1211 and 1301. A clean gas fire extinguishing agent that meets the requirements of the NFPA-2000 specification formulated by the National Fire Protection Association (NFPA) is characterized by a non-conductive and highly volatile gaseous fire extinguishing agent that leaves no residue during use. At the same time, heptafluoropropane clean fire extinguishing agent is harmless to the environment, has a short shelf life in nature, high fire extinguishing efficiency, and is non-toxic and harmful at a certain design concentration. It is suitable for use in protected areas where staff are stationed. It and carbon dioxide are both the main products to replace halocarbons.
Heptafluoropropane is one of the earliest developed halon alternatives in China. Its performance is similar to halon, which is in line with people's long-term habit of using halon fire extinguishing systems, and its fire extinguishing efficiency is also high. Heptafluoropropane is currently used in halon alternative products. The clean gas fire extinguishing system with the largest number and relatively mature technology.
