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.
