Known as the King of Solid Lubricants MoS2, hexagonal crystal molybdenum disulfide lubricant is widely recognized for its exceptional high temperature and heavy load molybdenum disulfide lubricant performance. As a premium extreme pressure solid lubricant, it perfectly solves the common failure of ordinary lubricants and lithium grease under high heat, heavy pressure and long-term friction. Its unique layered molecular structure adopts weak van der Waals force bonding, which allows internal atomic layers to slide freely during operation, forming a dense and heat-resistant protective film on metal surfaces to isolate direct contact and stabilize friction reduction.

The high-temperature lubrication stability of molybdenum disulfide powder is mainly affected by purity, impurity content and particle size uniformity. Excess iron, silica and other impurities will cause abrasive wear and accelerate grease oxidation at high temperatures, while unreasonable particle size leads to poor dispersion and lubricating film defects. To solve these problems, we provide full-series micron grade MoS2 powder with 98% high purity and low impurity control, perfectly compatible with lithium complex grease.

Our graded MoS2 powder D50 particle size covers full micron specifications for diverse extreme-pressure scenarios. The coarse 16-30μm coarse micron MoS2 powder adapts to heavy-load mining machinery and steel mill equipment. The 12-16μm medium grade is ideal for automotive chassis and construction machinery lubrication. The 3-6μm fine micron molybdenum disulfide suits precision mechanical rails and mold anti-seize scenarios, while the 1-1.5μm ultra fine molybdenum disulfide powder fits high-speed miniature precision bearings.

As a professional high purity molybdenum disulfide powder manufacturer, our low-impurity molybdenum disulfide for lithium grease effectively delays grease deterioration, greatly improving high-temperature anti-wear and anti-seize performance. It is a premium industrial solid lubricant additive and reliable molybdenum disulfide anti seize paste raw material, providing customized particle size lubrication solutions for various extreme pressure industrial environments.
