Tungsten Disulfide (WS2) 二硫化钨  适合的材料组合减摩涂层塑料/塑料，塑料/金属，塑料/皮革，皮革/皮革带在低负荷缓慢运动或振动。

Tungsten Disulfide (WS2) is dry/solid lubricant powder and is one of the most lubricious substance in world. WS2 offers excellant dry lubricity (COF: 0.03) unmatched to any other substance, including Graphite or Molybdenum Disulfide (MoS2).

Tungsten Disulfide (WS2) can also be used in high temperature and high pressure applications. It offers temperature resistance from -450 deg F (-270º C) to 1200 deg F (650º C) in normal atmosphere and from -305 deg F (-188º C) to 2400º F (1316º C) in Vacuum. Load bearing ability of coated film is extremely high at 300,000 psi.

Tungsten Disulfide (WS2) can also be used instaed of Molybdenum Disulfide (MoS2). See comparison of WS2 / MoS2

Since the powder offers one of the lowest Coefficient of Friction (Dynamic @ 0.03 & Static @ 0.07), the applications are unlimited and could be tried with every conceivable idea. .
