what are the uses of hydrofluoroethers?

As a third-generation CFC substitute with zero ODP, low GWP and short atmospheric residence time, hydrofluoroether is characterized by low toxicity, non-corrosive, non-flammable, non-fume generating, and good material compatibility, etc. It is widely used in many fields such as medical care, electronics, metals, precision instruments, optical lenses, communications, and aviation and aerospace.

(1) Used as cleaning agent

Due to low surface tension and viscosity, good permeability, and moderate solubility, it has good cleaning effect, and can be used to clean the particle impurities of precision electronic parts; clean FOUPs (front-open standard wafer box); clean LCD/OLED displays, optical parts and lenses; clean semiconductor etching chamber and parts; remove the residual buildup of fluorine; and clean automobile engine parts; Cleaning of communication equipment and aviation engines, oxygen pipeline equipment; cleaning of medical equipment parts.

(2) Used as a solvent

As a solvent, hydrofluoroether has low viscosity and surface tension, easy to spread and wet evenly, and easy to dry quickly, non-flammable, good material compatibility, can be used as a medium for airtightness test and voltage resistance test; electronic coatings, screen coatings diluent; fluorine oils, fluorine resins, fluorine coatings diluent; ignition point adjuster of flammable solvents; reaction solvents and analytical extraction solvents.

(3) Used as refrigerant

Hydrofluoroether has the advantages of excellent electrical characteristics, wide range of applicable temperature, small absolute viscosity in the range of ultra-low temperature region, non-flammable, high chemical stability, good material compatibility, etc. It can be used as refrigerant; dry etching device, photolithography device, ion spraying device, probe and information processing device temperature control refrigerant; immersion refrigerant in data center; immersion refrigerant in power device; it can be used as cooling device in food industry, Freeze-drying, freezing and pulverizing of rubber and plastic, cooling devices for chemical industry and pharmaceutical industry.
