Rokolub 50-B-100 is a polyalkylene glycol obtained by propoxylation and ethoxylation of the starter. The product is in a colourless to yellow liquid form. It is soluble in water and contains antioxidants (excluding BHT). The product (ISO VG 100) has a kinematic viscosity at 40 ° C in the range of 94-110 cSt and has a high viscosity index (VI> 220). The product has a high flash point of 250 ° C.

Rokolub 50-B-100 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. The product retains fluidity at temperatures below -40 ° C, which allows to obtain low temperature properties. Thanks to these features, the product is multi-season and can be used without temperature limits, especially where water-free systems for lubricating machines and mechanical devices are required.

The main application advantages of Rokolub 50-B-100:

  • less tendency to create sediments allows to keep the machines and devices lubricated,
  • reduced tendency to form deposits compared to mineral oils,
  • the possibility of using the product as a lubricant in devices operating in variable conditions, also at low temperatures (flow temperature Tp <-40 ° C),
  • compatibility of Rokolub 50-B-100 with NBR and EPDM elastomers and insolubility in mineral oils.

The most common applications of Rokolub 50-B-100:

  • lubricating oil used for gas compressors and refrigerant compressors,
  • component for the production of processing fluids and machining fluids for metals in various industries,
  • hydraulic fluids, base oil for the formulation of gear oils,
  • used as a component for the production of anti-foaming agents.

Products manufactured on the basis of Rokolub 50-B-100 are characterized by high, repeatable quality. Thanks to the refined production process, this product is characterized by excellent parameters and a wide range of possible applications.
