CXF-160, a single-phase electronic coolant chemically known as perfluorononenyl trifluoroethyl ether, is a high-boiling-point perfluoroether electronic fluorinated fluid. It is a colorless, odorless, transparent liquid widely used in precision cleaning, solvent thinners, and in the preparation of polymers and synthetic surfactants. It is a green, colorless, odorless, non-flammable, and highly insulating electronic cleaning agent, fluorocarbon solvent, and coolant. Due to its excellent environmental performance, safety, high electrical insulation properties, low dielectric constant, non-flammability, high thermal conductivity, and stable inertness, CXF-160 has been widely used as a full-immersion single-phase liquid coolant in major data centers, energy storage stations, and electronic products. It can also be used for live cleaning of communication base stations and low-voltage electrical cabinets.
