- Polyolester, abgekürzt POE, sind veresterte mehrwertige Alkohole (Alkohole mit mehreren Hydroxygruppen), die heute insbesondere als Schmierstoff für FKW-Kältemittel verwendet werden. Diese Kältemittel besitzen eine mehrpolare Eigenschaft und mischen sich deshalb mit mineralischen Ölen nicht, bzw. in zu geringem Maße. Ein Nachteil dieser Esteröle ist, dass sie eine hohe Affinität auch zu anderen polaren Stoffen, vor allem Wasser, haben. (de)
- Polyolester oil (POE oil) is a type of synthetic oil used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A and R-12. HFC-134a with POE oil as the lubricant is a replacement for CFC-12 with mineral oil as the lubricant. as HFC-134a does not mix well with mineral oil. These wax-free oils are suggested for use with chlorine free HFC systems as they provide better lubrication and stability and are more miscible with HFC refrigerants. They can meet the lubricity requirements to those of mineral oils used with CFCs and HFCs. They are compatible with most lubricants in the market. It is noted that the viscosity of the oil decreases with temperature. The dispersion behavior of this oil has also been the subject of a lot of study. It is also considered by some to be a good additive to engine oil. (en)
