The difference between molybdenum disulfide grease and graphite grease

2021-11-02 14:39:21  News

The most obvious feature of molybdenum disulfide grease is that the appearance is black, and it cannot be adjusted to other colors, because it is a lithium-based grease with additives such as molybdenum disulfide MoS2; but it is not a black grease. The grease that contains molybdenum disulfide may also be graphite-containing grease; so many people will confuse molybdenum disulfide grease with graphite grease.

So what is the difference between these two greases?

Molybdenum disulfide grease is a cost-effective high and low temperature synthetic grease made of low-viscosity PAO and molybdenum disulfide. It has the effect of anti-wear and extreme pressure, can carry heavy loads, and also has good thermal stability and lubrication. It has good compatibility with most plastics, effectively reduces the noise from plastic gears, has a long service life, and has low seepage.

Graphite grease is a kind of graphite grease made from synthetic oils thickened by inorganic thickeners and added with ultra-fine graphite powder, anti-oxidation, anti-corrosion and other additives. This ultra-high temperature grease will slowly volatilize the base oil when the temperature is above 200℃, and graphite will adhere to the lubricating surface to form solid lubrication. It is specially used for the lubrication of high temperature friction parts and bearings under heavy load/impact load or humid/polluted environment. Maximum rust and corrosion protection.

As explained above, although molybdenum disulfide and graphite are the same additives as grease, graphite grease mainly has outstanding high temperature performance, while molybdenum disulfide grease has outstanding anti-wear and extreme pressure performance, and graphite grease has two advantages Not as good as molybdenum disulfide grease.

Performance characteristics of molybdenum disulfide high and low temperature grease

Outstanding extreme pressure resistance, anti-vibration performance and wear resistance, strong load-bearing capacity;

Excellent lubricity, adhesion, corrosion resistance, water resistance and moisture resistance;

Good high temperature and low temperature resistance, no dilution or burning-out phenomenon at high temperature;

Excellent oxidation resistance, particularly low evaporation loss and a long service life.

Used for rollers and bearings that work under high temperature, high load or severe cold conditions, hot fan bearings, high temperature conveyor belt bearings, high temperature bearings for textile machines, high pressure roller presses, moving guide grooves, universal joints, spline shafts, screw rods lubricating.

It is used for the lubrication of heavy-duty gears, turbines and vortex rods in clearance operation.

Used for lubrication of high-load friction parts such as automobile chassis, steering system rack and pinion, and slot structure.

Used for the lubrication of high-load parts of industrial equipment (threads, screw caps, bushings, fasteners, couplings, shaft pins of transmission belts).
