PIB in fuel and oil as additive

Both conventional PIB’s (C-PIB) and high reactive PIB’s (HR-PIB) are used in lube oil as a dispersant in the form of polyisobutenyl succinate and polyisobutenyl succinamide. Using detergents, dispersants help minimize smoke and engine deposits.

More than 65% of world’s polyisobutene production is used in the lubrication industry. This includes engine oils, metal working fluids and industrial lubes.


Polyisobutene (PIB) in two-stroke oil and four-stroke oil

Conventional PIB’s with a molecular weight of approximately +/- 940 g/moll are used in two-stroke oil to clean exhaust gasses. The PIB acts as an attractant of dirt which arises during the process of burning petrol and oil in an engine. By adding PIB to the two-stroke oil the emergence of smoke will decrease.  Besides two-stroke oil PIB is also used in four-stroke oil because of its good shear.


Polyisobutene (PIB) in metal working fluids (greases)

PIB is used in the metal working industry as a lubricant. The PIB sticks to the metal, what results in a good lubrication on parts with friction. PIB is also used in this industry for foiling, stamping, cutting and pressing.


Polyisobutene (PIB) as fuel additive

Only high reactive polyisobutene (HR-PIB) is used as a fuel additive. It is primarily used as a dispersant in the form of polyisobutylamine, polyisobutylene, succinimide, polyisobutylene and phenylamine.
