Abstract
A lubricant composition is described. The novel lubricant composition has superior thermal stability, and can reduce the need to replenish the lubricant. The lubricant composition includes at least a soap component, a thickener component, an oil component, and a spherical polyolefin component (optionally Microthene). The spherical polyolefin component includes polyolefin microparticles.

A lubricant composition comprising:
- 1-10 wt. %, based on the total weight of the lubricant composition, of a soap component,
- 1-6 wt. %, based on the total weight of the lubricant composition, of a thickener component,
- 74-97 wt. %, based on the total weight of the lubricant composition, of an oil component, and
- wherein the oil component comprises a spherical polyolefin component, wherein the spherical polyolefin component comprises microparticles and wherein the polyolefin microparticles are EVA (ethylene-vinyl acetate) copolymer particles.
