Product description:

Molybdenum Disulfide (MoS₂) is a black or dark gray powder known for its excellent lubricating properties. It features exceptional thermal stability, low friction coefficient, and high load-bearing capacity, making it ideal for extreme working conditions such as high temperature, high pressure, vacuum, and corrosive environments. MoS₂ is chemically inert, provides long-lasting lubrication, and maintains performance under both dry and boundary lubrication conditions. It can be used alone or as an additive in oils, greases, polymers, and metalworking formulations.

Product Applications:

Molybdenum disulfide is widely used in the automotive industry and the mechanical industry.

  • Used as a solid lubricant for extreme conditions: high/low temperature, high load, high speed, corrosion, and vacuum.
  • Added to lubricants, grease, PTFE, nylon, paraffin, and stearic acid to reduce friction and enhance lubrication.
  • Extends lubrication cycles, lowers maintenance costs, and improves equipment performance.
  • Serves as a release agent for non-ferrous metals and a lubricant for forging dies.

Why choose our Molybdenum Disulfide ?

Four Particle-Size Grades

Coarse, Technical, Technical Fine, and Super Fine grades support different formulation and dispersion requirements.

Controlled Impurity Levels

MoO₃, iron, acid insolubles, water, oil content, and acid number are controlled according to grade specifications.

Reliable Lubrication Performance

Suitable for high-load, high-temperature, vacuum, and other demanding lubrication environments.

Technical Documentation Support

TDS, SDS, COA, grade specifications, and available batch documentation can be provided for technical evaluation and procurement.

Frequently Asked Questions

Grade selection mainly depends on particle-size requirements, dispersion behavior, formulation type, surface finish, and the intended lubrication system. Finer grades are generally preferred where tighter dispersion or smoother films are required.
MoS₂ has a layered crystal structure that allows the layers to shear easily over one another, helping reduce friction under dry and boundary lubrication conditions.
ZXCHEM supplies four grades, ranging from Coarse Grade with D50 16–30 μm to Super Fine Grade with D50 ≤0.7 μm.
Yes. MoS₂ can be incorporated into materials such as PTFE, nylon, paraffin, and other polymer systems where improved lubricity and wear performance are required.
