Tungsten Disulfide Podwer

Description

Tungsten disulfide WS2 is a compound of tungsten and sulfide, black powder, insoluble in water and organic solvents, reacting with neither acid nor alkali besides the mixture of thick 

Low friction coefficient (0.03), anti-pressure and anti-oxidation (in air decompose at 4500 C and completely at 6500 C; in vacuum decompose at 11000 C and completely at 20000 C). It can be used at high temperature, high pressure, high vacuum, high load, high rotating speed, ultra-low temperature, high radiation and corrosion conditions.

Application
WS2 superfine powder is a new lubricating material with excellent lubrication performance. It can be used as an additive to high temperature lubricating grease. The grease with the WS2 powder has good performance, such as high dropping point, high oil film strength(PB), and low friction coefficient. It can also be applied to anti-friction material in carbon brush industry,super rigidity material and weld thread; and also be applied to solid lubrication in spaceflight (-270ºC~+1300ºC, only WS2 can endure these temperatures required in cosmic lubrication), used in aviation, etc
