How to chooce the right Oil?<br />
Viscosity: the viscosity has a drastic impact concerning<br />
the processing behaviours<br />
Density: with constant viscosity the density increases<br />
by increasing aromatic content<br />
Both key properties are linked by the<br />
constant of density and viscosity (VGC)<br />
VGC =<br />
Density - 0,24 x 0,022 log (viscosity - 35,5)<br />
0,755<br />
The higher the VGC the higher the aromatic content<br />
