Rokolub 50-B-150 is a polyalkylene glycol (PAG) obtained by means of the starter propoxylation and ethoxylation. The product has liquid form ranging from transparent to light yellow colour. It is water soluble and contains (BHT free) antioxidants. The kinematic viscosity of the product (ISO VG 220) at the temperature 40°C ranges from 240 to 275 cSt and its viscosity index is high (viscosity index ~234).

Rokolub 50-B-150 may be used for production of synthetic lubricating oils as PAG type, group V, base stock, as well as a finished product. This polyol is water soluble at the temperature of 20°C. Based on this the product it may be used as synthetic PAG type base oil for high-performance lubricant formulations.

Main application advantages of Rokolub 50-B-150:

  • Reduced tendency for sludge forming enables maintaining cleanliness of the machines and equipment lubricated;
  • Reduced tendency for deposit or varnish forming compared to mineral oils;
  • High viscosity index and temperature stability;
  • Excellent lubricating properties not requiring application of refining additives;
  • Provides higher level of thermal conductivity;


Most frequent applications of Rokolub 50-B-150:

  • Lubricating oil used for gas compressors and industry gears;
  • Component for production of service fluids and metal working fluids in various industries;
  • Hydraulic fluids, base oil for gear lubricant formulations;
  • Anti-foaming agents;
  • Plasticiser for rubber and plastics;


Products made based on Rokolub 50-B-150 are of high, repeatable quality. Based on the optimally developed manufacturing process this polyol is distinguished by very good parameters and a wide range of possible applications.
