What Is Synthetic Lubricant?


The synthetic lubricant is a high molecular compound made by chemical synthesis method and then blend or further Processing to become the Synthetic lubricant. The synthesis is divided into six categories: organic ester, synthetic hydrocarbon, polyether, polysiloxane (silicone oil), fluorine oil and phosphate ester.

Synthetic Oil performance:

Compared with Mineral oil type lubricants, it has the following performance. The first property is the high-temperature performance. The synthetic lubricant is better than Mineral oil type lubricant in the thermal stability. The thermal decomposition temperature, the flash point, and the spontaneous ignition point are high. And the thermal oxidation stability is good, also allow to be used at a higher temperature.

In second, it has excellent viscosity-temperature performance and low-temperature performance.

In third, most synthetic lubricants have the higher viscosity index than Mineral oil type lubricant. And the viscosity changes with temperature are very small. When the high-temp viscosities are same, the pour point (or solidification point) of most synthetic lubricants is lower than that of Mineral oil type lubricant. Also, the low-temperature viscosity is small.

The fourth property is the low volatility. The synthetic lubricant is a kind of pure compound generally with a narrow boiling point and low volatility, thus it can extending the service life of oil products. The fifth property the excellent chemical stability. The synthetic lubricant has great use value in the national defense and chemical industry.

The sixth property is the non-flame property. The seventh property is the good radiation resistance. Some synthetic lubricants have excellent radiation resistance. And the last property is the adaptability to rubber sealing element.
