| Authors: | Xie Liangsen Li Hui |
| Abstract: | This paper illustrates the thickening effects of diureas and tetraureas formed from monoamines, diamines and diisocyanates on the mineral oils of different viscosity, and on the esters and polysiloxanes of different structures. It also reviews the properties and applications of such greases based on polyureas. |
