High-purity octafluorocyclobutane (C₄F₈) gas supplied from China for semiconductor manufacturing, electronics, and specialty applications.
High-purity octafluorocyclobutane (C₄F₈) gas for semiconductor etching, cleaning processes, refrigerant blends, and specialty gas mixtures.
Octafluorocyclobutane is a colorless, non-flammable, and environmentally friendly specialty gas with stable chemical properties. It is non-toxic, harmless, and features a low Global Warming Potential (GWP) and zero Ozone Depletion Potential (ODP). As a perfluorocarbon compound, it remains stable and does not react with other substances under normal conditions. Octafluorocyclobutane serves as a specialized etching and cleaning gas in semiconductor manufacturing, a component in refrigerant blends, and a dielectric gas for various electronics applications. It is also used in plasma processing and as a tracer gas, typically transported as a liquefied compressed gas.
