About MoS2 Dry Powder Lubricant

Molybdenum disulfide powder (also Moly powder or MoS2) is one of the best known solid dry lubricants. The chemical substance gained notice by aerospace and military applications, but nowadays it is found in a variety of tribological systems. It is widely used as an extreme pressure (EP) additive for greases and assembly pastes, in fluid lubricants like industrial gear oils, in dry solid film lubricants including bonded coatings.

Molybdenum disulfide exists in two crystalline forms, but the most common one is the hexagonal one. The hexagonal form is by far the most common and being the only type found in widely available ores. Also, the hexagonal form has been found in synthetic MoS2 Powder.


Areas of Use

For sliding properties improvement of machine parts, apparatus and precision machinery, and for parts with very strict tolerances.
As an additive for thermo plastics, seals, packages, sintered metals and improvement of E.P. sliding properties.
Long term lubrication in a variety of uses.


Benefits of Moly Powder

Reduces friction and wear in a wide temperature range (-290°F to +840°F).
Not electrically conducting.
Not magnetic.
Chemically stable except in contact with halogenated gases, neat sulphuric acid or nitric acid.
Highly effective due to elevated affinity of MoS2 (Molybdenum disulfide) to metals.
Low friction at high load carrying capacities.
Low consumption because of thin sliding layer.
