Can PAG be used in refrigeration oil?

Low-viscosity polyether (PAG) oils have good compatibility with HFCs and can be used as base oils to produce refrigeration oils.

 

PAG as a base oil for refrigerators with special gases: It is suitable for automobile air-conditioning compressors of R134a and other HFC products. It is used as a base oil for refrigeration compressors. After being matched with R134a in a certain ratio, it has good high-temperature and low-temperature solubility. The high-temperature solubility temperature is 0-80°C and the low-temperature solubility temperature is 0-60°C.

 

Its advantages as a refrigerator base oil are as follows:

① Unique polyether end-capping technology, with R134a and various HFC refrigerants have excellent solubility; ② Intrinsic water repellency, not easy to produce capillary freezing problem;

③ Excellent viscosity index, can form a stable lubricating film at high temperature, with good lubricity;

④ Low viscosity at low temperature, with good fluidity and solubility;

⑤ Stable chemical properties, in high temperature and high humidity conditions There is also less decomposition.
