NA-LUBE ® EP 5000 Series - Extreme Pressure AdditivesNA-LUBE ® EP 5000 SeriesExtreme Pressure / Antiwear AdditivesThe NA-LUBE EP 5000 Series consists of low odor, light-colored fatty acid esters, sulfurized fattyacid esters/triglycerides, and sulfurized α-olefins/triglycerides.Light-colored, low odor sulfur-containing additives are primarily produced by using hydrogen sulfideand elemental sulfur. The reaction is usually performed under high pressure and high temperatureconditions. Light-colored, low odor sulfur-containing additives have improved properties over thewell-known “black” sulfur-containing additives, including significantly improved oxidative stability andbetter solubility in highly paraffinic base oils.Sulfur-containing additives are commonly known in the lubricant and grease industry as “sulfurcarriers”. The different raw materials used for the production of these additives have a significantimpact on the properties and performance of the different sulfur carriers. Products based on shortchainolefins, such as isobutylene, can be called “dry” sulfur carriers because they only provideEP/AW properties; while those based on esters and triglycerides (fatty oils) can be called “wet”sulfur carriers because they also improve boundary lubrication.One of the most important characteristics of sulfur carriers is sulfur activity as measured inaccordance with the ASTM D 1662 test. The active sulfur content primarily depends on thepolysulfide chain length in the molecule. Sulfur-containing additives with a very low active sulfurcontent (6%) primarilyprovide extreme pressure properties.The NA-LUBE EP 5000 Series is manufactured from carefully selected raw materials to optimizeproduct quality and performance. Precisely controlled manufacturing processes result in productsthat are of light color and low odor.ProductNA-LUBEEP-5210NA-LUBEEP-5216NA-LUBEEP-5218NA-LUBEEP-5310NA-LUBEEP-5316NA-LUBEEP-5415% TotalSulfur% ActiveSulfurViscosity@ 40ºC(cSt)10
