Product Name: Dihydrocarbyl Pentasulfide Alias: Sulfurized extreme pressure additive, Vulcanized olefin extreme pressure agent Brand: RUNLUBE 8540 CAS.No.:68515-88-8 Physicochemical properties Composition: Dihydrocarbyl pentasulfide Color (ASTM D1500): about 2.0 Appearance: low viscosity light color liquid Active sulfur content (ASTM D1662): about 38 (Wt%) Sulfur content: about 40 (Wt%) Flash point C°C (ASTM D92): about 150°C Density 20ºC (ASTM D941): about 1.01G/ML Viscosity 40ºC(ASTM D445): about 50mm2/s Corrosion of metallic copper 4% in paraffin oil 100ºC1H (ASTM D130): 4c Application: RUNLUBE 8540 is the first domestically produced high-end active sulfur extreme pressure agent. Because of its inherent active sulfur content, the temperature also increases slightly with the increase of temperature, and it will show a significant extreme pressure effect; if it is used in combination with other sulfur agents and phosphate ester anti-wear agents, it will be better. Improve extreme pressure performance and anti-wear performance. At the same time, as an excellent extreme pressure agent, it is widely used in metalworking fluids, metalworking oils, lubricating oils and greases. Packing specification: 200kg/drum.
