Octafluorocyclobutane (C4F8) is a kind of special gas with stable performance, which has been widely used in many fields such as electronics, chemical industry, aerospace and refrigeration. Refrigerants and air conditioning: octafluorocyclobutane has a high thermal conductivity and heat capacity, can quickly absorb heat at low temperatures, so that the object to be cooled quickly, so it is used as a refrigerant and air conditioning. Fire extinguishing agent: octafluorocyclobutane is an excellent fire extinguishing agent, with high efficiency, non-toxic, pollution-free and other characteristics. It can quickly extinguish fire sources and effectively protect personnel and property safety. Cleaning agent: octafluorocyclobutane is also an excellent cleaning agent, with good solubility and volatility, can quickly clean a variety of surface dirt and grease. Electronics industry: In the electronics industry, octafluorocyclobutane is mainly used in etching and cleaning processes. It can also be used as a gas insulating medium, solvent, spray, blowing agent, large-scale circuit etching agent, heat pump working fluid and raw material for the production of C2F4 and C3F6 monomers. Other fields: In addition to the above applications, octafluorocyclobutane is also used in the production of fluorine-containing polymer compounds, fluorine-containing fine chemicals, etc.
