Description

Rokolub 68 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. This polyol is water insoluble. During its manufacturing process Rokolub 68 BHT antioxidants are added. The kinematic viscosity of Rokolub 68 (ISO VG 68) at the temperature 40°C ranges from 60 to 70 cSt. The product is marked by viscosity index is high (viscosity index i VI>150), which ensures good lubricity of the systems without major load, not requiring application of refining additives. 

Group V base stock commonly used based on its wide range and easy application. It is used, a.o.,  PAG type synthetic lubricating oil.

Main application advantages of Rokolub 68:

  • Cleanliness of the machines and equipment lubricated based on the reduced tendency for sludge forming;
  • Significantly reduced tendency for sludge forming enables maintaining cleanliness of the machines and equipment lubricated;
  • Possibility of using the polyol as a lubricant for equipment operating under variable conditions, including at low temperatures (pour point Tp<-36°C);
  • Compatibility of Rokolub 68 with NBR and EPDM elastomers;

 

Most frequent applications of Rokolub 68:

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

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