Tungsten Disulfide application:
Tungsten Disulfide can be used as an additive for high-temperature grease. After adding WS2 powder, the grease has excellent properties such as high dropping point, high oil film strength and low friction factor. Also used as a colored, black brush additive in the carbon industry. It can also be applied to super-hard materials and wire materials, as well as to aerospace (-270 ° C ~ 1300 ° C, WS2 can resist this temperature in the universe lubrication), solid lubrication in aviation, military and other fields.

Storage Condition of Tungsten Disulfide WS2 Powder:
Damp reunion will affect WS2 powder dispersion performance and using effects, therefore, Tungsten Disulfide WS2 Powder should be sealed in vacuum packing and stored in cool and dry room, the Tungsten Disulfide WS2 Powder can not be exposure to air. In addition, the WS2 powder should be avoided under stress.
