Colloidal Stability of Greases Based on Oils with Organic Thickening Agents

Colloidal stability of greases is one of the most important physicochemical parameters, which characterizes their working capacity and affects the mechanical strength and tribological properties. An integrated study of the colloidal stability of greases based on synthetic base oils with organic thickening agents demonstrated that the stability depends to a noticeable extent on quite a number of factors, such as the nature of a base oil and a thickening agent, presence of fillers, synthesis conditions, etc. A combination of these factors makes it possible to obtain greases with required colloidal stability.
