SUMICO Moly Powder PA Molybdenum Disulfide Solid Lubricant Powder
Moly Powder PA 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. Moly Powder PA has an average particle size of approximately 5.2 μm, positioned between the finer PS grade and the coarser PB grade. Its molybdenum disulfide content is approximately 98.2 wt%, making it suitable for formulations requiring a medium-particle-size MoS₂ additive.
Product Details
Product Features
Medium Particle Size: Moly Powder PA has an average particle size of approximately 5.2 μm, between PS at 1.4 μm and PB at 23 μm.
High MoS₂ Content: Contains approximately 98.2 wt% molybdenum disulfide for solid lubrication and friction-control applications.
Low Friction: Representative coefficient of friction is approximately 0.04, helping reduce friction at sliding interfaces.
Improved Wear Resistance: When blended into sliding materials, it can help improve wear resistance in plastics, rubber and friction materials.
Wide Temperature Capability: Reference service temperature range 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 parts, gears and toothed belts to improve wear resistance and sliding performance.
Rubber: Suitable as an additive in rubber and composite formulations to improve friction and sliding characteristics.
