Sentence examples for viscosity index from inspiring English sources

The less the viscosity is changed by temperature, the higher the viscosity index.

Since little change of viscosity with fluctuations in temperature is desirable to keep variations in friction at a minimum, fluids often are rated in terms of viscosity index.

However, flash point and viscosity index decrease as the percentage of diesel increases.

Six copolymers, based on polyacrylates, were prepared and evaluated as viscosity index improvers for lube oil.

Pour point depressant (PPD) and viscosity index improver (VII) properties were tested with additive doped base oil in terms of pour point (PP) and viscosity index (VI), respectively.

A non-dimensional viscosity index indicated an increase in relative viscosity for every 1% reclaimed asphalt binder.

Samples with different concentrations from each copolymer (0.5%, 1%, 1.5%, 2%, 2.5%, 3% by weight) were prepared and evaluated as viscosity index improvers for lube oil.

The results revealed that the developed octyl esters have improved viscosity index, pour point, flash point and oxidation stability when compared to that of the raw material (WCO).

This test was carried out to optimize feed and product quality for the commercial Base Oil unit to produce high viscosity index (VI) lube oil.
