Polyalphaolefin (420 g/mol) (320 C)

Polyalphaolefin (PAO) is a synthetic hydrocarbon polymer used as a base oil in high-performance lubricants. It does not have a single fixed chemical formula because it is a mixture of oligomers derived from alpha-olefins (commonly decene). It appears as a clear, colorless, and odorless viscous liquid. It is highly stable, non-polar, and has excellent thermal and oxidative stability with very low volatility.
In terms of uses and applications, Polyalphaolefin is widely used in the lubricant and oil industry as a high-quality synthetic base oil for engine oils, gear oils, hydraulic fluids, and compressor oils. It provides superior performance at both high and low temperatures. It is also used in industrial lubricants, greases, and metalworking fluids due to its excellent lubricity and stability. In the automotive and aerospace sectors, it is used for advanced synthetic lubricants requiring long service life. Additionally, it finds application in specialty fluids, refrigeration oils, and high-performance machinery lubrication systems.
