Application:  It is mainly used in environments that require heat resistance, chemical resistance, solvent resistance, corrosion resistance, toxicity resistance, flammability resistance, and have requirements for lubrication life. It can also be formulated into grease with PFPE for use in the lubrication fields of chemical engineering, electronics, military, nuclear, aerospace, and other special requirements. In recent years, it has been highly favored as a liquid cooling medium for data centers.

Thermal-oxidative stability: Even in the presence of oxygen and without the action of a catalyst, PFPE remains stable within the range of 270 to 300 ℃, and its obvious decomposition temperature can reach 350 to 550 ℃.

Chemical inertness: PFPE does not react with most corrosive chemical reagents such as inorganic acids, inorganic bases, organic acids, organic bases, halogens and oxidants, etc., demonstrating extremely strong chemical inertness.

Compatibility: PFPE has excellent compatibility with many substances, such as fuels, plastics, rubbers, metals, coatings, etc., and thus has an extremely wide range of applications.

Non-flammability: Compared with other types of lubricants, PFPE is more suitable for high-temperature and harsh operating environments.

Dielectric properties: PFPE has excellent dielectric properties, featuring high dielectric strength, high resistivity, and low dielectric constant.

Physiological inertness: PFPE has no toxic effect on human organs. Through oral and skin contact tests on animals, PFPE are found to be low in toxicity and have no adverse effects.

Low volatility: At the same viscosity, PFPE has a much lower vapor pressure than hydrocarbon-based lubricating oils, with minimal evaporation loss, ensuring a longer service life.

Excellent friction performance: PFPE has excellent lubrication capabilities. The inorganic-organic double-layer film formed by PFPE on the steel surface is an important reason for its anti-wear property. Since the formed organic film is a plow flow lubrication film, it can reduce the direct contact between the friction pairs, thereby reducing friction and wear; on the wear marks on the steel surface, a double-layer film of metal fluorides and polymers is covered, and the fluoride film on the wear marks belongs to the boundary lubrication film, which can reduce the friction coefficient.
