Properties:

Tungsten disulfide (WS2) as a solid lubricant has remarkable characteristics in terms of physical properties, and petroleum-based oils and greases were most commonly used as lubricants in the past.

 

In recent years, with the advancement of industrial technology, the demand for new solid lubrication has increased with the increase in machine output, rotation speed, sliding speed, load, and use in harsh environments such as high temperature and vacuum. It is also very important to maintain a clean atmosphere and protect the environment.

 

Tungsten disulfide (WS2) has an oxidation temperature about 100°C higher than molybdenum disulfide (MoS2), has excellent heat resistance and extreme pressure properties, and has a lower coefficient of friction.

 

Tungsten disulfide (WS2) resists high surface pressure! Among solid lubricants, its coefficient of friction tends to decrease with increasing load.

 

Tungsten disulfide is also lubricious at high temperatures of 450°C, helping to prevent sintering or seizure.

 

Tungsten disulfide (WS2) is more wear resistant! Relevant durability tests have shown that molybdenum disulfide is at least three times as durable.

 

Tungsten disulfide (WS2) is very clean and environmentally friendly! Reduce industrial waste and protect the environment.

 

Tungsten disulfide (WS2) has a very good energy-saving effect! In addition to reducing energy consumption through a lower coefficient of friction, it also extends component life, saving energy and reducing costs. It acts as a lubricant in the temperature range of -273°C to 450°C in the air, and it is inert, inorganic, non-toxic, and non-corrosive. It is compatible with most oils and greases. Compared with graphite, MoS2 and Teflon, the surface deposits are reduced by half.
