Application:

Polyurea greases are prepared by thickening mineral oil or synthetic oil with organic compounds containing polyurea groups in the molecule. Polyurea thickeners are different from soap-based metal (calcium, sodium, lithium) thickeners and do not contain any metals. Typically, their operating temperature range is higher than greases based on metal soaps. Due to the nature of polyurea, they have better antioxidation and anti-abrasion properties. Their other advantages are: pumpability, oxidation resistance, mechanical stability, colloidal stability and water washing, high temperature and load tolerance. Polyurea grease has very good wear resistance and prevents direct contact with the surface of the teeth, so it can effectively extend the service life of the device.
