Perfluorohexanone FK5112 is a new type of environmentally friendly clean fire extinguishing agent, used to replace a series of fire extinguishing agents such as Halon, hydrofluorocarbon compounds (HFC) and perfluorocarbon compounds (PFC). As a liquid storage Chemicalbook, it is discharged in the form of gas when used, leaving no residue and being non-conductive, helping to protect paper documents and electronic products with preservation value. It has good environmental properties, does not damage the atmospheric ozone layer, and has an extremely low GWP value.
