Viscosity Modifier

The viscosity modifier produced from the polybutenes has the advantage that shows the change of viscosity in accordance with the temperature of the lube oil. 


Automotive and industrial oils often need thickening agents to achieve the correct viscosity.

Polybutenes (PIBs) often replace bright stocks to obtain the required viscosity. They also have the advantage of raising the viscosity index of the thickened lubricant.

PIBs also lower the pour point.

For this purpose, KEMAT Polybutenes are selected for their good shear stability and to assure that the viscosity of the thickened lubricant will remain stable under normal conditions.

If combined, with high-viscosity poly alpha olefins (PAOs) or synthetic esters, KEMAT Polybutenes also lower the deposit formation, give cleaner burning and also tackiness will improve while the cost can be decreased.

End User Applications

PIB/PAO mixtures provides 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.
