Molybdenum disulfide powder, also called MoS2 powder or moly powder, is a dry solid lubricant material used to reduce friction and improve load-carrying performance in grease, oil, coatings, resin, rubber and metalworking applications. It is used when a low-friction solid film is needed under load, especially in demanding mechanical systems.
Why MoS2 Works as a Solid Lubricant
MoS2 has a layered crystal structure. Under load, the layers can slide over each other and help form a low-friction solid lubricating film.
Particles Enter Contact Area
MoS2 particles are carried by grease, oil, or dry application between two metal surfaces.
Layers Align Under Load
The lamellar sheets of MoS2 align parallel to the direction of motion under pressure, like a deck of cards sliding over each other.
Solid Film Reduces Wear
A low-friction solid film is formed, preventing direct metal-to-metal contact and reducing wear marks.
Typical Characteristics of Morelic Molybdenum Disulfide Powder
The properties below indicate typical directions for MoS2 powder. Final values depend on the specific grade, purity, and particle size selected for your project. Please confirm exact specifications with the latest Morelic TDS.
| Property | Typical Direction / Reference | Why It Matters |
|---|---|---|
| Composition | S=Mo=S | Ensures fundamental lubricating properties and structural stability under shear. |
| Specific Gravity | 4.8 | Determines settling rates in dispersions and affects overall formulation density. |
| Color | Grayish black | Provides visual confirmation of solid film coverage and uniform distribution on parts. |
| Coefficient of Friction | 0.04 | Delivers exceptional anti-wear performance and minimizes energy loss in moving parts. |
| Load Resistance | Approx. 30,000kg/cm² | Prevents metal-to-metal contact, scoring, and galling under extreme pressure (EP) conditions. |
| Temperature Conditions | -180°C~400°C | Maintains lubrication integrity and structural form across extreme thermal environments. |
| Chemical Resistance | Excellent (except from Aqua regia, hot sulfuric acid, and hot nitric acid) | Protects critical components in aggressive chemical, solvent, and corrosive environments. |
| Heat Resistance | -180°C~400°C in atmosphere, and up to 1090°C in inert gases. | Enables reliable operation in high-temp industrial applications without degrading. |
| Corrosion Resistance | Anti-fretting | Extends the operational lifespan of metal components by forming a protective barrier against rust and oxidation. |
| High Vacuum Resistance | Maintains excellent lubrication even in high vacuum of 10-8 torr or higher, as well as under high-density radiation. | Indispensable for reliable performance in aerospace, semiconductor, and high-vacuum equipment where other solid lubricants fail. |
Where Molybdenum Disulfide Powder Is Used
Morelic supplies specific MoS2 powder grades tailored for different industrial formulations and manufacturing processes.
Lubricant Additive
Serves as a high-performance additive to significantly improve the lubrication and load-carrying properties of greases, lubricating oils, and dry film coatings.
Friction Materials
Acts as a critical additive to enhance wear resistance, stabilize friction coefficients, and improve the physical properties of brake pads and friction linings.
Resin & Rubber
Compounded into resin, rubber, and polymer matrices to inherently improve self-lubricating performance and reduce mechanical wear.
Wire Drawing & Forming
Applied directly or formulated as a robust solid lubricant for wire drawing, cold heading, and severe plastic forming operations.
Choose MoS2 Powder by Particle Size
The right MoS2 powder should be selected by particle size, purity, dispersion requirement, carrier system, and final application.
Super Fine MoS2
Typical Particle Direction: submicron to around 1–2 µm class.
Best For: fine grease dispersion, oil dispersion, thin coating, precision additive systems.
Buyer Note: Better dispersion potential but requires oxidation and storage review.
Technical Fine MoS2
Typical Particle Direction: around 4–6 µm class or custom fine grade.
Best For: general grease additive, coating, polymer compound, friction material.
Buyer Note: Balanced choice for many lubricant additive projects.
Technical MoS2
Typical Particle Direction: larger technical grade, application-specific.
Best For: dry solid lubrication, heavy-duty industrial use, wire drawing.
Buyer Note: Useful where particle size tolerance allows larger powder.
Custom Grade
Based on customer TDS or target formulation.
| Application | Suggested Starting Grade | Key Check |
|---|---|---|
| Grease additive | Super Fine / Technical Fine | dispersion, oil separation, additive compatibility |
| Oil additive | Super Fine / Fine | suspension stability, filtration, sedimentation |
| Coatings | Fine / Technical Fine | film thickness, surface finish, binder compatibility |
| Resin / Rubber | Fine / Technical Fine | dispersion, compound processing, color impact |
| Friction materials | Technical Fine / Custom | formula compatibility, friction behavior |
| Wire drawing / forming | Technical / Custom | load, process speed, surface finish |
| Dry lubrication | Technical Fine / Technical | surface roughness, application method, environment |
