Extreme Pressure Additives

Extreme Pressure Additives:

• The extreme pressure additives are sulfured compounds, chlorinated compounds and phosphorus-sulfur derivatives: – Sulfinated products, such as fatty esters with high sulfur concentration react at high temperature leading to the formation of a protecting layer of iron sulfur.

Applications:

• Extreme Pressure additives are usually used under heavier loads, at high temperatures and low speeds to prevent catastrophic failure or seizing of the application. Common examples of Extreme Pressure additives are molybdenum disulfide, graphite, sulfurized olefins and dialkyldithio carbamate complexes.
