Viscosity modifiers are additives in a lubricant used to minimise the variations in viscosity of the lubricant as a function of temperature
Automotive and industrial oils often need thickening agents to achieve the correct viscosity. Viscosity modifiers are a component of numerous oils. At low temperatures the viscosity increases at a lower rate than most oils. At high temperatures the viscosity decreases at a lower rate than most oils. PIB is often used to replace bright stocks and high viscosity base oils as a viscosity modifier. PIB also lowers the pour point.
If combined, with high-viscosity poly alpha olefins (PAO) or synthetic esters, KEMAT Polybutenes also lower the deposit formation, give cleaner burning and also tackiness will improve while the cost can be decreased.
PIB/PAO mixtures provide superior viscometrics over the standard PAO products mostly used in high performance industrial oils, greases, and compressor lubricants.
In the mixture PIB/synthetic esters the PIB acts as an effective viscosity modifier for the ester. The use is mainly in high-performance two-stroke lubricants, industrial oils, greases and chain lubricants.
