Description

Rokolub 680 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 insoluble and contains (BHT free) antioxidants. The kinematic viscosity of the product (ISO VG 680) at the temperature 40°C ranges from 570 to 620 cSt and its viscosity index is high (viscosity index VI>260).

Rokolub 680 may be used for production of synthetic lubricating oils as PAG type, group V, base stock, as well as a finished product. Based on its high viscosity index this polyol ensures excellent lubricity in systems without major load, and not requiring application of refining additives.

Main application advantages of Rokolub 680:

  • 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;
  • Compatibility of Rokolub 680  with NBR and EPDM type elastomers and insolubility in mineral oils

 

Most frequent applications of Rokolub 680:

  • Lubricating oil used for refrigeration compressors;
  • Component for production of service fluids and metal working fluids in various industries;
  • Hydraulic fluids, base oil for gear lubricant formulations;
  • Plasticiser for rubber and plastics;

 

Products made based on Rokolub 680 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.
