Rokolub 50-B-46 is a polyalkylene glycol obtained by propoxylation and ethoxylation of the starter material. The product is available in the form of 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).

The product (ISO VG 46) has a kinematic viscosity at 40 ° C in the range of 45-55 cSt and is characterized by a high viscosity index (viscosity index VI> 210). The product is also characterized by a high flash point, above 240 ° C.

Rokolub 50-B-46 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 enables obtaining low temperature properties. As a result, this all-season product can be used without temperature limits.

The main application advantages of Rokolub 50-B-46:

  • less tendency to form sludge and varnish deposits makes it easier to maintain cleanliness of lubricated machines and devices (in comparison to mineral oils),
  • possibility of using as a lubricant in devices operating in variable conditions, also in low temperatures (flow temperature Tp <-30 ° C),
  • compatibility of Rokolub 50-B-46 with NBR and EPDM elastomers and insolubility in mineral oils.

The most common applications of Rokolub 50-B-46:

  • component for the production of processing fluids and cutting fluids for various industries,
  • product used in the production of heat transfer fluids,
  • hydraulic fluids, base oil for the formulation of transmission oils.

Products manufactured on the basis of Rokolub 50-B-46 are characterized by high, repeatable quality. Thanks to the refined production process, the product is characterized by excellent parameters and a wide range of possible applications.
