Firstly, Y-type perfluoropolyether oil is more stable compared to K-type perfluoropolyether oil, with a high temperature resistance of over 300 degrees Celsius, and stronger oxidation resistance, corrosion resistance, and stability under high temperature conditions. Of course, this also means that its price is relatively high, so it is commonly used in the industrial field.

K-type perfluoropolyether oil, on the other hand, has even better lubrication effects. It has good compatibility with metals and almost all chemical substances, and can provide long-term stability for some special machinery and equipment. At the same time, it also has good cutting lubrication and diffusion transparency characteristics. K-type perfluoropolyether oil has a wide range of applications, not only suitable for high temperature and high load environments, but also for low temperature, high speed, and normal temperature environments.
