The article presents the results of the use of viscous additives based on polyisobutylene to improve the performance of railway greases LZ CNII. It is established that the introduction of this type of additives into the dispersion medium of lubricants allows to increase their colloidal stability and tribological properties without deterioration of the operational parameters essential for the application of these lubricants.

Keywords: plastic lubricant, friction, thickener, polyisobutylene, wear resistance, grease film, reliability
