Abstract

A friction material composition may include an abrasive, a filler, a binder, and a spherical molybdenum disulfide powder. The spherical molybdenum disulfide powder is made up of molybdenum disulfide sub-particles that are agglomerated together to form individual, substantially spherically-shaped agglomerated particles of at least about 90% by weight molybdenum disulfide.
