Rokolub 150 is a polyether polyol obtained by means of the starter propoxylation. The product has a form of homogenous, clear liquid at the temperature of 25°C. It is water insoluble and it contains BHT-free antioxidants. The kinematic viscosity of Rokolub 150 at the temperature 40°C ranges from 135 to 160 cSt, with very good low temperature properties.

This viscosity index of this polyol is high (viscosity index VI > 170) , which ensures good lubricity in systems without major load, not requiring application of refining additives,  provides a wide application range in various industries. Rokolub 150 is classified as a polyalkylene glycol and it is used for production of synthetic lubricating oils, as PAG type, group V base stock, or as a finished product.

Main application advantages of Rokolub 150:

  • Wide range of application as a lubricant in equipment operating at variable temperatures – good low temperature properties (pour point  Tp<-36°C)
  • Reduced tendency for deposit forming ensures maintaining higher cleanliness of the machines lubricated;
  • Compatibility with NBR and EPDM elastomers;
  • Reduced tendency for sludge and varnish forming compared to mineral oils;


Most frequent applications of Rokolub 150:

  • Hydraulic fluids and oils;
  • Component for production of service fluids and metal working fluids;
  • Lubricating oil for gas compressors and refrigeration compressors;
  • Anti-foaming agents;

Products made based on Rokolub 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.
