High-purity heptafluoropropane (C₃HF₇) gas supplied from China for fire suppression, refrigeration, and specialty applications.
High-purity heptafluoropropane (C₃HF₇) for clean agent fire suppression systems, refrigerant blends, and aerosol applications.
Heptafluoropropane is a colorless, tasteless, non-toxic, and non-conductive clean agent fire extinguishing gas. As a hydrofluorocarbon (HFC), it provides both chemical and physical fire suppression, making it highly effective without leaving residues or causing damage to sensitive equipment, electronics, or precision instruments. It is also used in refrigeration systems, as an aerosol propellant, and in various specialty applications. Heptafluoropropane is typically stored and transported as a liquefied compressed gas.
