What is the Difference between POE Oil and Mineral Oil?

POE oil (Polyolester Oil) is a synthetic oil, which is synthesized by esterification of polyols and fatty acids, and is a polar oil. In contrast, mineral oils are natural oils derived from petroleum.

Here are their main differences:

Different chemical properties: POE oil is a synthetic oil with high polarity and chemical stability, which can maintain lubricating performance in a wide temperature range. Mineral oil is a natural oil that is relatively unstable chemically.

Different functions: POE oil has good heat resistance and oxidation resistance, and can still maintain good lubricating performance under high temperature and high load conditions. The lubricating performance of mineral oil is relatively poor, and it is easy to decompose and oxidize under high temperature and high load conditions.

The impact on the environment is different: POE oil is a biodegradable oil with less impact on the environment, while mineral oil is not easy to degrade and has a greater impact on the environment.

The price is different: the price of POE oil is relatively high, while the price of mineral oil is relatively low.

In practical applications, POE oil is often used in lubricating systems with high temperature, high load, high speed or high cleanliness requirements, such as compressors, refrigeration equipment, etc. Mineral oil is often used in general lubrication systems, such as machine tools, transmission systems, etc.
