The product is an AW / EP type lubricant (antiwear / extreme pressure) used to ensure high lubricity. Rokolub AD 246 plus is an essential anti-wear and anti-friction additive in oil formulations intended for use at high temperatures. It provides a reduction of friction between moving parts, which effects in equipment wear reduction. In addition, the product prevents machine seizure in the event of a load resulting in boundary friction.
The operation of AW/EP type additives consists in forming on the surface of steel elements a polymer lubricating film. Phosphate esters are reacted with oxides and metal hydroxides (especially with iron compounds) that are found on the surface of the metals, forming multilayer lubricating coatings. As a result, the friction of individual components and the device wear are reduced.
Excellent anti-wear properties of aryl phosphate esters are confirmed by the results of the four-ball tests. Adding 2% of Rokolub AD 246 Plus to mineral oil provides reduction of the defect diameter by up to 50%. The product also improves the wear resistance of synthetic oils. Rokolub AD 246 Plus also positively affects the anti-friction properties of lubricating oils. It works effectively with other EP additives (phosphor, sulphur, chlorine), providing surface protection in friction junctions, especially in sliding contact of materials. Due to its good compatibility with other additives for oils, it can be successfully used as a component of the additive package.
Rokolub AD 246 plus is a phosphoroorganic ester in the form of a light yellow to colourless liquid. It has a very low water level and a low acid value, which ensure long-term stability of the product's parameters. In turn, the high phosphorus content gives the product unique properties that are important in the lubricating oil industry. The products of the Rokolub AD series are phosphate additives, which, in contrast to the widely used sulphated and chlorinated AW/EP additives, do not cause corrosion and staining of metals. Rokolub AD 246 Plus, in comparison to AW/EP additives based on aryl organic esters, is characterized by a lack of risk to human health.
The product is used as an additive for industrial oils (hydraulic oils, compressor oils, turbine oils, gear oils), industrial greases as well as metal working fluids.
PCC Rokita SA is one of the largest chemical companies in Poland as well as Central and Eastern Europe. Its activity includes the production of chloroalkali, polyether polyols, polyalkylene glycols and phosphorus derivatives.
