Rokolub® WS 680 is a mixture of polyether polyols and is used as a base oil or additive for formulations of lubricants. It is soluble in water. Product viscosity class according to ISO VG is 460. It has kinematic viscosity at temp. 40°C within the range of 437-483 cST and is characterised by high viscosity index: VI~251.
Rokolub® WS 680 is characterized by high temperature of ignition >220 ⁰C. It is used as a base oil of the PAG type included in group V to manufacture synthetic lubricants, and also as a finished product. It maintains fluidity in temperature below -22°C which allows obtaining good low-temperature properties. Owing to this the product is all-weather and can be used without temperature-related limitations mainly in such places where anhydrous lubrication systems for machines and mechanical equipment are required.
Reverse solubility in higher temperatures allows creation of durable film on the surface of the machined metal which makes the product exceptionally useful in formulations for heat treatment of metals as cooling and lubricating liquids.
Main advantages of application of polyol Rokolub® WS 680:
high viscosity index,
excellent lubricating properties – reduced characteristics of wear and tear of
materials and increased resistance to very high pressures,
allows keeping machines and equipment clean, does not leave oily deposits,
