Current and future polyalphaolefins

Polyalphaolefins currently have a market share of less than 1 per cent in Europe, but this is expected to double in the next 5 years. This paper looks at additive response, rheology, volatility, and oxidation resistance of PAOs; of particular importance are their low temperature capabilities. The results of various tests are given, in comparison with mineral-based oils. In conclusion, research is under way to investigate the possibilities of ‘tailor-making’ PAOs by varying production process variables and using a variety of starting olefin streams.
