MOLYBDENUM DISULFIDE
Molybdenum Disulfide
Molybdenum disulfide is a solid lubricant, known as the "king of solid lubricants". It is silvery black powder. It is widely used as a dry lubricant because of its low friction and robustness.
Molybdenum disulfide can be added in grease to increase the lubricity and extreme pressure of grease. Molybdenum disulfide can be used in high temperature, high pressure, high speed and high load environment to extend the life of equipment.
The main function of molybdenum disulfide is to reduce friction at low temperature, increase friction at high temperature, and reduce burning loss.
