Rokolub AD 246 is an AW/EP type lubricant used to improve lubrication capacity of mineral and synthetic oils of POE and PAO type. This product is an essential anti-wear and anti-friction additive in oil formulations designed for high temperature operation. Provides reduced friction of moving parts and reduces equipment wear. In addition, it prevents machine wear in the event of boundary friction.
The operation of AW/EP type additives consists in forming on the surface of steel elements a polymer lubricating film. Phosphoric 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 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 also positively affects the anti-friction properties of different types of oils. It works effectively with phosphoric, sulfuric, chlorine EP additives, 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 series products are phosphate additives which, in contrast to widely used sulphated and chlorinated AW/EP additives, do not cause corrosion and metal staining. Due to the reaction of hydrolysis of esters in an acid or alkaline medium, this product is characterized by low water level and low acid value. Rokolub AD 246 also has a high content of phosphorus, which determines the unique properties of the product used in the lubricating oil industry. Rokolub AD 246 in comparison to A /EP additives based on aryl organic esters is characterized by a lack of risk to human health.
The product is used as an additive to industrial oils (hydraulic oils, compressor oils, turbine oils, gear oils), industrial greases, 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.
