Key MoS2 Nanopowder Properties and Applications
Key Material Characteristics
- 90 nm stated average particle size for applications requiring nanoscale MoS2.
- 99.0% stated purity.
- Specific surface area of 35 m²/g.
- Nearly spherical stated morphology.
- Approximately 0.78 g/cm³ bulk density and 5.06 g/cm³ true density.
- Molybdenum disulfide is a dry/solid lubricant material with a hexagonal lamellar crystal structure at the material-family level.
- The MoS2 product family is used in lubricant, coating, polymer and vacuum-related lubrication applications.
Common Application Areas
MKN-MoS2-090 may be evaluated for:
- Lubricant, oil and grease additive formulations.
- Dry-film and solid-lubricant research.
- Coating and paint formulations.
- Polymer and compatible composite formulations.
- High-load or extreme-pressure lubrication research.
- Vacuum and inert-atmosphere lubrication research.
- Industrial and laboratory materials research.
Final suitability depends on particle dispersion, concentration, carrier medium, substrate, surface preparation, humidity, load, temperature and operating conditions. Application testing is recommended before production use.

Important: These are general molybdenum disulfide product-family reference values from the MoS2 brochure. They are not batch-specific performance test results for MKN-MoS2-090. Actual performance depends on formulation, substrate, dispersion, application method, humidity, load and operating conditions.
Safety, Handling and Storage
Store Molybdenum Disulfide Nanopowder in a tightly closed container, in a dry and well-ventilated location. Avoid dust and aerosol formation. Avoid breathing airborne material. Ensure adequate exhaust ventilation where dust may be generated.
Wear suitable gloves and safety glasses with side shields. Respiratory protection should be selected in accordance with the exposure level and relevant workplace requirements. The SDS refers to P95/P1 for particulate protection for nuisance exposure and for higher-level respirator cartridges where greater protection is needed.
WARNINGThe current SDS for molybdenum disulfide powder classifies it for acute inhalation toxicity, Category 4, with the signal word “Warning” and the following hazard statement: “Harmful if inhaled.” The SDS also lists possible respiratory tract, skin and eye irritation and states that ingestion may be harmful. Before handling or using the product, read.
The substance is stable at recommended storage conditions. Strong oxidizers or hydrogen peroxide should not be used.
Transport
The current SDS lists molybdenum disulfide powder as “Not dangerous goods” under DOT, IMDG and IATA transport classifications. This transport classification should not be interpreted as meaning that no handling precautions are required.
