Graphite grease is a lubricating grease suitable for heavy duty and resistant to very high pressures and temperatures. It is used in lubrication of gears, bearings, ropes and metal cables. Thanks to its good electrical conductivity, however, it is also used for various tasks such as the greasing of electric battery terminals for cars and sliding contacts. Sometimes it is used to protect the threads though for this task it is more suitable for the fat.
It is an extreme pressure (EP) grease in which graphite crystals are dispersed. These crystals act as solid lubricants and wrap the lubricated surface to reduce friction if the grease film is damaged due to high pressures. It supports temperatures above 700 ° C, is resistant to moisture and water, exhibits strong adhesion to metallic surfaces and has anti-rust and antioxidant properties. Sometimes molybdenum bisulphide is added.
Graphite particles have a lamellar shape whose overlapping tendency guarantees highly resistant lubricant veils, while molybdenum disulfide particles have spherical shape, are incomprehensible and have excellent lubricating properties. To incorporate them into fatty pasta, however, serve as carriers to suspend and disperse them, and detergents to prevent mites; carriers and detergents are the weak side of this type of fat since their features over time tend to degrade.
