Methyl perfluoroisobutyl ether (CAS: 163702-08-7) is a colorless, transparent, non-flammable, low-toxicity, and eco-friendly fluorinated ether solvent. Its core advantages include low surface tension, low viscosity, fast drying, high insulation, and zero ozone depletion potential. It is widely used in electronics cleaning, heat transfer, precision manufacturing, and daily chemical applications.
Key Product Features
1.Safety & Eco-friendliness: Non-flammable, non-toxic, ODP=0, and low GWP. It complies with environmental regulations and serves as a viable substitute for traditional solvents like trichloroethylene and n-propyl bromide.
2.Superior Cleaning Performance: The combination of low surface tension and low viscosity ensures strong cleaning power against oil, flux, particulates, and fingerprints. It dries quickly with no residue, making it ideal for precision cleaning.
3.Insulation & Heat Transfer: Features high dielectric strength, allowing for live-line cleaning (cleaning while energized). Its high heat transfer efficiency makes it suitable as an electronic fluorinated fluid or immersion liquid cooling medium.
4.Moderate Solvency: Exhibits good solvency for fluorocarbons, silicone oils, and greases, while showing weak solvency for polar substances. This makes it perfect for selective cleaning and formulated solvent applications.
5.Stability: Possesses strong chemical inertness; it is resistant to acids and alkalis and does not decompose easily, ensuring stable performance during long-term use.
