China Wholesale Sulphur Tetrafluoride Sf4 Factories – Octafluorocyclobutane (C4F8) – Taiyu

Technical Parameters

Octafluorocyclobutane is a chemical substance, a perfluorinated derivative of cyclobutane, and its chemical formula is C4F8. Colorless, odorless, non-flammable gas. Stable in nature and non-toxic. In case of high heat, the internal pressure of the container will increase, and there will be a risk of cracking and explosion. The combustion (decomposition) product is hydrogen fluoride. Octafluorocyclobutane is very stable and does not react with other substances under normal conditions. The storage and reaction vessel can be made of cast iron and stainless steel at 120°C, and steel can be used at 175°C. When it exceeds 400°C, Inconel Materials such as, nickel and platinum can also be slightly damaged. At 500°C, these materials have a catalytic effect on decomposition. At high temperatures (600°C), octafluorocyclobutane can decompose into carbon, carbon tetrafluoride and toxic compounds. Octafluorocyclobutane has a very wide range of applications. In recent years, it has been widely used as a refrigerant to replace prohibited chlorofluorocarbon compounds. In addition, it is also commonly used in gas insulating media, solvents, sprays, foaming agents, and large-scale circuit etchants. , Heat pump working fluid and raw materials for the production of C2F4 and C3F6 monomers. High-purity octafluorocyclobutane (above 5N) is used as an etching agent and cleaning agent for VLSI circuits. Due to its stable properties, non-toxicity, zero ozone depletion potential (ODP), and good insulation, octafluorocyclobutane has been widely used in technical fields such as high-voltage insulation, cleaning and etching, and plasma treatment in recent years. Emergency response to leakage: wear self-contained breathing apparatus and work clothes. Cut off the gas source. Ventilation and convection, dilution and diffusion. Move the leaking container to an open area and pay attention to ventilation. Leaking containers can no longer be used, and must undergo technical treatment to remove the remaining gas.
