Rokolub 100 is a polyether polyol obtained by means of the starter propoxylation. The product is marked by high flashpoint, low residue volume and biodegradable condensate. The product has liquid form ranging from transparent to light yellow colour.  Rokolub 100 is a water insoluble polyol containing BHT-free antioxidants.

This polyol has high viscosity index, which ensures good lubricity in systems without major load, not requiring application of refining additives.  The kinematic viscosity of Rokolub 100 (ISO VG 100) at the temperature 40°C ranges from 90 to 100 cSt, with very good low temperature properties

This Polyol has a wide range of application as PAG type synthetic base stock. Similar like other oils from this group, Rokolub 100 is applied especially wherever waterless lubrication systems for machines and equipment are required. Based on its superior properties Rokolub 100 is a polyalkylene glycol used for production of synthetic lubricating oils, as group V base oil or as a finished product.

Because of its chemical properties this product is suitable also for contact with food.

Main application advantages of Rokolub 100:

  • Maintaining its flow power at the temperature below -31°C;
  • Low temperature properties making the product suitable for year-round use;
  • Possibility of using the polyol as a lubricant in equipment operating at variable temperatures;
  • Compatibility of Rokolub 100  NBR and EPDM type elastomers;
  • Thanks to the reduced tendency for forming deposits and sludge compared to mineral oils, this polyol ensures better cleanliness of the equipment lubricated;
  • Excellent lubricating properties – reduced consumption profile and high pressure resistance;
  • Excellent lubricating properties not requiring application of refining additives;
  • Repeatable quality;


Most frequent applications of Rokolub 100:                       

  • Waterless lubrication systems for machines and mechanical equipment;
  • Lubricating oil for gas compressors;
  • Hydraulic fluids, components for production of  service fluids and metalworking fluids;
  • Anti-foaming agents;

Products made based on Rokolub 100 are of high, repeatable quality, and very good parameters, based on the optimally developed manufacturing process.
