Description

Rokolub P-B-46 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 46) at the temperature 40°C ranges from 42 to 50 cSt and its viscosity index is high (viscosity index VI>180).

Rokolub P-B-46 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 below -40°C, which provides 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 P-B-46:

  • 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;
  • Possibility of using the polyol as a lubricant for equipment operating under variable conditions, including at law temperatures (pour point Tp<-40°C);
  • Compatibility of Rokolub P-B-46 with NBR and EPDM type elastomers and insolubility in mineral oils

Most frequent applications of Rokolub P-B-46:

  • 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 P-B-46 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.
