Modified polyisobutylene succinimide dispersants having improved seal, sludge, and deposit performance
A composition suitable for reducing sludge and degradation of elastomer seals in engines comprises an oil of lubrication viscosity and a minor amount of a sludge preventing/seal protecting nitrogen containing dispersant, which is a reaction product of a hydrocarbyl-substituted succinic acylating agent having a limited amount of low molecular weight substituent; and a polyamine or condensed polyamine containing less than 20 mole percent of polyamine components of 6 or fewer nitrogen atoms.
Recommended Products
T161 is a high molecular weight ashless dispersant prepared from highly reactive isobutylene(Mn=2300) by thermal adduction process. It has excellent dispersancy & solubilization effect on oil sludge and soot; and can effectively control the increase of the engine oil viscosity . It doesn’t contain chlorine.
Features
Excellent dispersancy of oil sludge at low temperature
Excellent soot dispersancy
Good detergent dispersancy
Free of chlorine
Application
Used for blending API SG and higher grade gasoline engine oils
Used for blending API CF-4 and higher grade diesel engine oils
Particularly suitable for blending environment-friendly engine oils
The reference dosage: 2.0%-5.0%
