FORMULATION APPROACH TO EXTEND THE HIGH TEMPERATURE PERFORMANCE OF LITHIUM COMPLEX GREASES

摘要

The present disclosure provides a lithium complex grease with high-temperature resistivity and a method of using the same. The lithium complex grease includes: a lithium complex thickener, a friction modifier, a polymer or copolymer, and at least one synthetic base oil with alkylated naphthalene. The lithium complex grease can be substantially free of polytetrafluoroethylene. Furthermore, the lithium complex grease provides a median failure rate via a ball bearing test (e.g., using the FE9 grease life test method of DIN 51 821) performed at 160° C. of no less than 100 hours.
