Rokolub 32 is a polyether polyol obtained by means of the starter propoxylation, with limited water solubility. The product has liquid form ranging from transparent to straw yellow colour. The product, with kinematic viscosity at 40°C ranging from 25 to 35 cSt, is marked by very good low temperature properties.

Rokolub 32, also known as polyalkylene glycol (PAG), is used for production of synthetic lubricating oils as PAG type, group V, base stock, as well as a finished product. The distinguishing features of Rokolub 32 obtained based on maintaining its flowing power at the temperature below -40°C, make the product suitable for year-round application. Based on its parameters and easiness to use this polyol is used wherever waterless lubricating systems for machines and mechanical equipment are required.

Because of its structure and properties this polyol is suitable for use in contact with food.

Main application advantages of Rokolub 32:

  • compatibility with NBR and EPDM elastomers,
  • cleanliness of the machines and equipment lubricated based on the product structure and chemical composition,
  • very good low temperature parameters enabling application at low temperatures,
  • easy application.

Most frequent applications of Rokolub 32:

  • production of heat transfer fluids,
  • hydraulic fluids, brake fluids, and cooling-lubricating fluids for metalworking,
  • lubricating oils for airbags,
  • phthalate-free plasticiser for rubber vulcanizing.

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