Molybdenum Disulfide For Lubricating Grease

Product Description

Introduction

Molybdenum Disulfide For Lubricating Grease is used as a powder system as a mold release agent, which has the advantages of high temperature resistance, wear resistance and tensile strength. In Molybdenum Disulfide For Grease a layer of molybdenum atoms is sandwiched between two layers of sulfur atoms. When Molybdenum Disulfide For Grease is dispersed between two metal surfaces, molybdenum disulfide binds to each metal surface through sulfur atoms, which hinders the contact of asperities (irregular parts of the metal surface), and sliding contact is in the sulfur atoms between the outer layers, the interaction between them is very weak. Therefore, the surfaces that bind Molybdenum Disulfide For Grease can easily slide against each other.

Molybdenum disulfide, as an outstanding solid lubricant additive, significantly enhances the comprehensive performance of lubricating greases. It is widely used in extreme pressure lubricating grease for heavy machinery, automotive chassis and high-load bearings. Under boundary lubrication conditions, molybdenum disulfide particles can form a stable solid lubricating film on the friction surface, effectively reducing friction and wear, enhancing the extreme pressure load-bearing capacity of the grease, and significantly extending the service life of equipment under harsh working conditions such as high temperature and heavy load. It is an indispensable key component of modern high-performance lubrication systems.
Research shows that adding an appropriate amount of molybdenum disulfide to grease can effectively enhance the high-temperature stability and extreme pressure performance of the /MoS₂ system, thereby expanding the application range of grease and meeting the requirements of various working conditions.

The friction coefficient is relatively low, and Molybdenum Disulfide For Grease can be lubricated for a long time in the air below 350 ℃.

Molybdenum Disulfide For Grease is a lubricant grade of molybdenum disulfide (MoS₂) available in two grades-Technical , and Technical Fine. Typical MoS₂ content (calculated average) is 98.5%.
