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.
