Functional characteristics：
● Tungsten disulfide (WS₂) as a solid lubricant has outstanding characteristics in terms of physical properties. Petroleum-based oils and greases are most commonly used as lubricants.
● 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. Maintaining a clean atmosphere and protecting the environment are also very important.
● The oxidation temperature of tungsten disulfide (WS₂) is about 100°C higher than that of molybdenum disulfide (MoS₂).
● It has excellent heat resistance and extreme pressure performance, and has a lower coefficient of friction.
● Tungsten disulfide (WS2) can resist high surface pressure!
● In solid lubricants, its friction coefficient has a tendency to decrease as the load increases.
● Tungsten disulfide is also lubricating at a high temperature of 450°C, which helps prevent sintering or seizing.
● Tungsten disulfide (WS₂) is more wear-resistant! Relevant durability tests show that the durability of molybdenum disulfide is at least three times that of it. 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 lowering the friction coefficient to reduce energy consumption, it can also extend the service life of components, achieve energy saving and reduce costs.
● In the air, it acts as a lubricant in the temperature range of -273°C to 450°C.
● It is inert, inorganic, non-toxic and non-corrosive. It is compatible with most oils and greases.
● Compared with graphite, MoS2and Teflon, surface deposits are reduced by half.
