Rokolub 60-D-220 is a polyalkylene glycol obtained by propoxylation and ethoxylation of a starter. The product is in the form of a homogeneous, colourless to yellow liquid. It is soluble in water due to the presence of ethylene oxide in the polymer chain, and contains antioxidants (excluding BHT).
The product (ISO VG 220) is characterised by kinematic viscosity at 40°C within the range 200-235 cSt, and high viscosity index (viscosity index VI> 230). Rokolub 60-D-220 has a high temperature turbidity point within the range of 70-95°C, depending on the molecular weight of the molecule.
Rokolub 60-D-220 may be used for the production of synthetic lubricating oils such as PAG type base oil belonging to the group V, as well as a finished product. The product retains its fluidity at temperatures below -35°C, which allows it to obtain good low-temperature properties. As a result, the product is multigrade, and may be used without temperature restrictions. At higher temperatures reversed solubility creates a permanent lubricating film on the surface of the cut metal. This feature makes the product extremely useful in formulations used as cutting oils for heat treatment of metals
The main advantages of Rokolub 60-D-220 application:
reduced tendency to form sediments allows to keep the lubricated machines and equipment clean,
reduced tendency to form carbon deposits and varnishes as compared to mineral oils,
option to use the product as a lubricant in equipment operating in variable conditions, also at low temperatures (flow temperature Ft <-35°C),
compatibility of Rokolub 60-D-220 with NBR and EPDM elastomers, and insolubility in mineral oils,
high viscosity index ensures oil fluidity, tightness in changing temperature conditions’ and lower oil consumption during a cold start.
The most common applications of Rokolub 60-D-220:
product used for the production of oils for glazing machines,
component for the production of working fluids and process fluids for metal in various industries,
product used for the production of compressor oils, non-flammable hydraulic fluids (HFDU), and as a liquid heat carrier,
used as a plasticizer for rubbers and plastics.
Products manufactured on the basis of Rokolub 60-D-220 are characterized by high, repeatable quality. Owing to a refined production process, this product is distinguished by very good parameters and a wide range of possible applications.
