Products

Property and application:
Under normal tempeature and pressure, Heptafluoropropane(HFC227ea)is a kind of colorless gas,and is a compressedliquefied gas to be stored in cylinders. Heptafluoropropane(HFC227ea)extinguishant is an ideal substitute of Halon 1301,and is clean,low poisonous,and has a good fire-protecting effect. It is mainly usede in total=flood extinguishing system.
