Rokolub® 75-D-18000 is a high-quality synthetic base oil of the PAG (polyalkylene glycol) type, soluble in water. It is intended for use as a base oil or viscosity-increasing additive (thickener/viscosifier) in high-grade synthetic lubricant and functional fluid formulations.
The product is characterized by very high kinematic viscosity at 40°C (14,400 - 21,600 cSt), a very high viscosity index (VI approx. 430) and a flash point above 240°C.
Rokolub® 75-D-18000 forms a durable, thick lubricating film, effectively reduces wear on rubbing parts, and provides high resistance to loads and high pressures. It is characterized by very good thermal and oxidative stability and shear resistance, as well as high thermal conductivity, which enables effective heat dissipation.
It reduces the formation of deposits and carbon deposits compared to mineral oils, helping to keep machines and equipment clean. Despite its very high viscosity, it retains good low-temperature properties - it remains pourable below 6°C, and in aqueous solutions even at sub-zero temperatures.
It is also available in versions containing 30% or 40% water, which facilitates dosing and handling.
Main application advantages of Rokolub® 75-D-18000:
very high viscosity index,
very good lubricating properties – reduced material wear and increased resistance to high pressures,
no oil deposits or carbon deposits – keeps machines and equipment clean, leaves no oil deposits,
high flash point.
Most common applications of Rokolub® 75-D-18000 polyol :
component for the production of metalworking fluids and process fluids,
component for the formulation of synthetic quenching fluids,
base oil for the formulation of HFC hydraulic fluids.
