Rokolub 50-B-460 is a polyalkylene glycol obtained by propoxylation and ethoxylation of the starter. The product is a colourless to light-yellow liquid. It is soluble in water due to the presence of ethylene oxide in the polymer chain and contains antioxidants (excluding BHT). Product (ISO VG 460) has a kinematic viscosity at 40 ° C in the range of 430-480 cSt and is characterized by a high viscosity index (VI> 250). The product has a high flash point above 240 ° C.

Rokolub 50-B-460 can be used for the production of synthetic lubricating oils as a PAG base oil belonging to the V group, as well as a finished product. It retains fluidity at temperatures below -30 ° C, which allows to obtain low temperature properties. As a result, the product is multi-season and can be used without temperature limits.

The main application advantages of Rokolub 50-B-460:


  • less tendency to create sediments and carbon deposits – in comparison to mineral oils – allows the cleanliness of lubricated machines and devices to be maintained,
  • possibility of using as a lubricant in devices operating in variable conditions, also at low temperatures (flow temperature Tp <-30 ° C),
  • Rokolub 50-B-460 is compatible with NBR and EPDM elastomers and insoluble in mineral oils.

The most common applications of Rokolub 50-B-460:


  • component for the production of processing fluids and machining fluids in various industries,
  • product used in the production of liquid heat carriers,
  • hydraulic fluids, base oil for the formulation of gear oils.

Products made on the basis of Rokolub 50-B-460 are characterized by high, repeatable quality. Thanks to the refined production process, the product has excellent parameters and a wide range of possible applications.
