For black powder, a metallic luster, as the "High-solid lubricants." MoS2 is natural molybdenum concentrate powder after the change in the chemical purification and molecular structure made of solid powder. The drug slightly silver-grey color black, metallic luster, a touch of flu smooth, insoluble in water. With a good spread of products, not a bit of bonding, MoS2 friction materials for the main function is to reduce friction when the low-temperature, high temperature by Moldova, and burned a small amount of loss in the friction materials in the volatile.
