SYG 556 PFPE Perfluoropolyether Grease

Perfluoropolyethers(PFPE) is a kind of special perfluorinated polymer compound, the average molecular weight is between 500～1500, and only 3 elements like C, F & O can be found in the molecule. It has good physical and chemical properties like: high temperature resistance, anti oxidation, non-flammable, non-volatile, low pour point, low surface tension, high dielectric, good lubricating property, chemical inertness, bio-inert, and etc. PFPE is mainly used in the working conditions with heat, chemicals, solvents, corrosive, toxic, flammable materials and the working condition has requirement for the life of the lubricants, as well. The grease made from PFPE oil can be used in chemical, electronic, military, unclear, aerospace industries, and other special lubrication areas.

1)Heat and oxidation stability: PFPE can keep stable under the condition with oxygen but without catalyst while the temperature is between 270-300℃, it will be broken down obviously under the temperature between 350-550℃

2)Chemical inertness: PFPE does not react with most corrosive chemical agents like inorganic acids, inorganic bases, organic acids, organic bases, halogens and oxidizing agents. So it has very strong chemical inertness.

3)Consistence: PFPE has good consistence with many materials like: fuel, plastic, rubber, metal, coating, and etc. Therefore, it has many extensive applications.

4)Non-flammability: compare with other lubricants, it is more suitable for high temperature and the hash working conditions.

5)Di-electrical property: PFPE has good di-electrical property, high dielectric strength, high resistivity, and low dielectric constant.

6)Physiological inert: PFPE has no toxicity to the organs of the human body, through oral test and skin contact experiment to the animals, the data shows PFPE has low toxicity and has no bad effects.

7)Low volatility: PFPE has lower vapor pressure than hydrocarbon lubricants with the same viscosity. The low volatilization ensures longer service time of the lubricants.
