Introduction
S40 is an EP additive with light color, low odor, high sulfur and high active sulfur content, suitable for heavy-duty processing occasions requiring rapid release of sulfur;
S40 shows excellent reactivity at lower temperature, and the active sulfur content gradually increases with the increase of temperature;
S40 has a good synergistic effect with many additives such as polymer ester and anti-wear agent, especially when it is combined with super high TBN Petroleum Calcium Sulfonate;
S40 has low viscosity and good compatibility with various base oils.
