Molybdenum Disulfide

Molybdenum Disulfide powder is considered as a solid lubricant additive in the production of EP high performance greases.

A number of unique properties distinguish molybdenum disulfide from other solid lubricants:

– A low coefficient of friction (0.03-0.06) which, unlike graphite, is inherent and not a result of absorbed films or gases;
– A strong affinity for metallic surfaces;
– Film forming structure;
– A yield strength as high as 3450 MPa (500 x 103 psi);
– Stability in the presence of most solvents;
– Effective lubricating properties from cryogenic temperatures to about 350°C in air (1200°C in inert or vacuum conditions).

Molybdenum disulfide will perform as a lubricant in vacuo where graphite fails.

Molybdenum Disulfide is able to provide the following characteristics:

  • Very high resistance to high loads and vibrations
  • Excellent corrosion protection
  • Water resistant

The addition level in special greases is between 2% and 20% depending on the properties that you want to give to the final product and depending on the final application application.

Available in different grades and purities up to 99% of MOS2 content; the main ones are:
