Description

Rokolub 220 is a polyalkylene glycol (PAG) obtained by means of the starter propoxylation. The product has liquid form ranging from transparent to light yellow colour. It is water insoluble and contains (BHT free) antioxidants. The product kinematic viscosity at 40°C ranges from 220 to 250 cSt, and it maintains the flowing power at the temperature below -20°C, which results in obtaining good low temperature properties. This makes the product suitable for year-round application without temperature limitations.

Rokolub 220, known also polyalkylene glycol, is used for production of synthetic lubricating oils as  group V PAG base stock, as well as a finished product. Based on its properties Rokolub 220 is suitable for food contact.

Main application advantages of Rokolub 220:

  • Product compatible with NBR and EPDM type elastomers;
  • Used as base oil provides cleanliness of the equipment and machines lubricated thanks to the reduced tendency for deposit, varnish and sludge forming compared to mineral oils;
  • Very good adaptation properties for operation at low temperature;
  • High repeatability level;

Most frequent applications of Rokolub 220 include:

  • Lubricating oils for industrial gears;
  • Oils for metalworking fluids;
  • Waterless lubrication systems for machines and mechanical equipment;
  • Lubricating oil for gas compressors;

Products made based on Rokolub 220 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.
