Bentone (also known as Organo-Clay or Non-Melting) Grease:

High temperature Grease

The key advantages include:

  • Very good high temperature performance - does not melt
  • Made from widely available commodity raw materials


  • Can age-harden
  • De-gels if mixed with mono-soap grease
  • Can dry into clay residue at high temperature when exposed to air

Manufacturing Principle:

Mix organo-clay with oil, mill then package.  Some Organo clays do not require heat, others need moderate heating, perhaps to about 80°C

Recommended Process Vessel(s):

  • Unheated or heated mixer
