Property is indexed. Possible indexes are from 1 to 50.

Measure for the viscosity of the fluid, the greater the viscosity, the more viscous (less flowable) the fluid is. This property is measured in Pascal-Seconds (Pa·s) or in the more common unit Millipascal-Seconds (mPa·s). Example: A lubricating oil has a viscosity of 100 mPa·s at 40 °C.
