- It is able to withstand high loads (EP: extreme pressure) due to the presence of sulfur which chemically reacts with the metals, preventing adhesive wear from contact.
- It reduces friction from sliding due to its hexagonal lamellar chemical structure.
- It functions up to 400°C, even in the presence of air.
It is produced with different particle sizes from 1 to 100 µm.
It is not commonly used in lubricating oils because it is hard to disperse, while it is widely used in greases and dried lacquers. Optimizing particle size and the concentration used in lubricants is extremely important for the following reasons:
- A low particle size promotes the uniform distribution of the product on the metal surface to be lubricated but may not adequately separate the roughness of the contact between part and counterpart. Therefore, a proportion of large granular particles is required.
- Too low a concentration may not be enough to reduce wear, too high a concentration might give compatibility problems with yellow alloys and worsen the stick-slip.
TecnolubeSeal has a full range of molybdenum disulfide lubricants. Below is a partial list:
- Rheolube 380: synthetic grease with molybdenum disulfide ideal for lubricating screw balls and/or medium and small gears.
- Fluorocarbongel 880 MS: high viscosity silicone grease able to withstand high loads due to the combination of PTFE and molybdenum disulfide.
- Fluorocarbongel 875 MS: PAO-base grease with molybdenum disulfide, ideal for kinematic lifetime lubrication lenses such as fifth wheels, gears and/or bearings.
- Spray Dry Moly: dispersion of molybdenum disulfide capable of forming a molybdenum disulfide oil-free “dry paint”.
