• Lubrizol 5340

Lubrizol 5340MW is an Extreme Pressure (EP) additive based on a sulfurized olefin.  It it contains 40% total sulfur and 36% active sulfur.  Suitable for use in neat oil and semi-synthetic metalworking fluids for cutting applications.


While Lubrizol 5340MW is an excellent product, it is Tri-iso's opinion that Rhein Chemie Additin RC 2540 represents a much better overall value.  Additin RC2540 is a direct drop-in replacement for Lubrizol 5340MW.  Specifically, Additin RC 2540 is an Extreme Pressure Additive based on dialkylpentasulfide. 40% total sulfur, 36% active sulfur, 50Cst @ 40C. Cu-Corr (3h/100C) 4b. Suitable for metal working fluids (cutting and forming), including water miscible metal working fluids. Shows synergistic effects to boost Extreme Pressure properties when combined with Additin RC2415 and synergistic effects to boost antiwear properties when combined with Zinc dithiophosphates (ZDDP) such as Additin RC 3038 and Additin RC 3880.
