Detailed description
Overview
Perfluorohexanone is an important alternative to halon fire suppressants. It is a fluoroketone compound—a clear, colorless, and odorless liquid that is supercharged with nitrogen and stored in high-pressure cylinders as part of a fire suppression system. Its chemical structure is identical to that of 3M’s NOVEC1230 fire-extinguishing fluid. Typical application areas include fire protection for computer rooms, data centers, aviation, ships, vehicles, libraries, and oil and natural gas production facilities. Another outstanding feature of perfluorohexanone as a fire suppressant is its exceptional environmental performance. It has an ozone depletion potential (ODP) of 0, a global warming potential (GWP) of 1, and an atmospheric lifetime of just 0.014 years (5 days). As a result, it can serve as a long-term and sustainable replacement for halons, hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs).
Perfluorohexanone is a liquid at room temperature. Due to its heat of vaporization being only one-twenty-fifth that of water and its vapor pressure being 25 times higher than water's, this substance readily vaporizes and exists in the gaseous phase. It primarily extinguishes fires by absorbing heat. In terms of environmental protection, it is truly an eco-friendly, green fire-extinguishing agent.
Since the extinguishing concentration of perfluorohexanone is 46%, it has a relatively high safety margin and is therefore safer for human exposure during use. Perfluorohexanone is a liquid at room temperature and does not qualify as a hazardous material, allowing it to be safely stored and transported in ordinary containers under atmospheric pressure over a wide temperature range—including by air transport—unlike other halon alternatives that require pressurized containers for storage and transportation. However, with a boiling point of 48–49°C, its application as a fire suppressant still has certain limitations. It is particularly suitable as a replacement for Halon 1211 fire extinguishers or for total flooding and localized application systems used for Class B fire protection.
The perfluorohexane fire suppressant rapidly vaporizes upon discharge, absorbing heat and cooling to extinguish fires. After discharge, it leaves no residue, is clean, exhibits excellent insulation properties, does not contaminate protected objects, and causes no damage to financial or precision equipment—making it an outstanding green and environmentally friendly fire suppression agent. It is effective in extinguishing Class A, B, and C fires, is non-corrosive to commonly used metallic materials, boasts superior insulation performance, and will not harm electronic components or circuits nor cause secondary damage. When paired with temperature-sensitive self-activating fire suppression systems, it is ideal for use in data centers, electronic control centers, advanced precision instrument facilities, communication base stations, substations, power grids, museums, archives, and other similar environments.
