Short sulfur chain = Less number of sulfur = More stable polysulfide = Less reaction with metal = Inactive Long sulfur chain = More number of sulfur = Less stable polysulfide = More reaction with metal = Active
Structure of sulfur EP
Chemical structures of carrier is used to control property. -Size of the structure: viscosity, solubility, sulfur content, lubricity -Chemical structure: reactivity, EP performance, stability, solubility

Primary function of DAILUBE products is prevention of seizuring and welding by formation of metal sulfide tribo-film. Some DAILUBE products also have significant effect to reduce friction by adsorption onto metal surface.
