Description

Rokolub 320K 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 320) at the temperature 40°C ranges from 350 to 375 cSt and its viscosity index is high (viscosity index VI>210).

Rokolub 320K may be used for production of synthetic lubricating oils as PAG type, group V, base stock as well as a finished product. This polyol maintains its flowing power at the temperature of -30°C, which provides very good low temperature properties. This makes the product suitable for year round application, without temperature limitations, especially where waterless lubricating systems are required for machines and mechanical equipment.

Main application advantages of Rokolub 320K:

  • Reduced tendency for sludge forming enables maintaining cleanliness of the machines and equipment lubricated;
  • Excellent lubricating properties not requiring application of refining additives
  • Reduced tendency for deposit or varnish forming compared to mineral oils;
  • Possibility of using the polyol as a lubricant for equipment operating under variable conditions, including at law temperatures (pour point Tp<-30°C);
  • Compatibility of Rokolub 320K with NBR and EPDM type elastomers and insolubility in mineral oils

 

Most frequent applications of Rokolub 320K:

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

 

Products made based on Rokolub 320K 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.
