SUMICO Moly Powder PS Molybdenum Disulfide Solid Lubricant Powder
Moly Powder PS is a molybdenum disulfide solid lubricant powder manufactured by SUMICO. It is designed for use as a solid lubricant and functional additive in sintered alloys, brake materials, friction materials, plastics and rubber, helping improve sliding and wear characteristics. Among the PS, PA and PB grades, Moly Powder PS has the finest average particle size at approximately 1.4 μm. Its molybdenum disulfide content is 98.1 wt%, making it suitable for formulations requiring fine-particle solid lubrication and good dispersion.
Product Details
Product Features
Fine Particle Size: Moly Powder PS has an average particle size of approximately 1.4 μm, making it the finer grade among PS, PA and PB.
High MoS₂ Content: Contains approximately 98.1 wt% molybdenum disulfide for solid lubrication and friction-control applications.
Low Friction: Representative coefficient of friction for MoS₂ is approximately 0.04, supporting improved sliding performance.
Improved Wear Resistance: When blended into sliding materials, it can help enhance wear resistance in plastics, rubber and friction materials.
Wide Temperature Capability: The reference service temperature range for MoS₂ is approximately -75°C to 400°C.
Good Chemical Resistance: Resistant to most chemicals except hot sulfuric acid, hot nitric acid and aqua regia.
Product Applications
Sintered Alloys: Used as a solid-lubricant additive to improve friction and wear properties in sintered metal materials.
Brake Materials: Suitable for brake and related friction-material formulations requiring controlled friction characteristics.
Friction Materials: Suitable for composite materials where stable friction performance is required.
Plastics: Can be blended into plastic sliding components, gears and toothed belts to improve wear resistance.
Rubber: Suitable as an additive in rubber and composite formulations to improve friction and sliding performance.
