Perfluorobutane is a high-purity perfluorinated alkane with outstanding inertness and environmental friendliness, widely used across electronic, fire suppression and aerosol industries. In electronics manufacturing, it serves as precision cleaning agent for semiconductor chips, circuit boards and optical components, effectively removing grease and particulate without corrosion to delicate electronic parts. It works as eco-friendly replacement for ozone-depleting CFCs and HCFCs in clean fire-fighting formulations for precision instrument, data center and electrical equipment fire protection. Additionally, it is adopted as foaming agent for high-end thermal insulation foam and propellant for medical aerosol inhalers, cosmetic sprays. In laboratory research, it functions as inert heat-transfer medium and fluorinated solvent carrier. Its zero ozone depletion potential and low global warming feature make it a mainstream environment-compliant fluorochemical in modern fine chemical and electronic industries.
GHS Classification: H280 (Contains gas under pressure; may explode if heated), H315 (Causes skin irritation for liquefied product), H319 (Causes serious eye irritation for liquefied liquid). Signal Word: Warning. Acute inhalation LD50 value is extremely high with low acute toxicity under normal concentration; high-concentration gaseous inhalation may cause suffocation by oxygen displacement in confined space. Rapid vaporization of liquefied perfluorobutane leads to cryogenic frostbite upon direct skin or eye contact requiring immediate cold water flushing. Operate in well-ventilated workshop; wear cryogenic-resistant gloves, splash-proof goggles and protective garments during cylinder filling and transfer. Avoid cylinder exposure under high temperature or open flame to prevent vessel rupture. Prevent arbitrary emission into enclosed low-lying space for suffocation risk control. Store gas cylinders fixed upright separately from combustible substances; discard waste gas following local fluorocarbon waste management regulations.
