Viscosity Index Improvers

Pour Point Depressants (PPDs) are specialty lubricant additives designed to improve the low-temperature flow properties of oils. They modify wax crystal formation within lubricant formulations, allowing oils to remain fluid and pumpable even in cold operating conditions.

Enhance Viscosity Stability Across Temp.

Viscosity Index Improvers (VIIs) are specialized polymer additives used in lubricants to minimize viscosity changes caused by temperature fluctuations. They help lubricants remain fluid during cold starts while maintaining adequate film strength at high operating temperatures, ensuring consistent protection and performance.

What Are Viscosity Index Improvers?

Viscosity Index Improvers are high molecular weight polymers that expand as temperature increases, reducing the natural thinning tendency of lubricants. These additives are essential in modern multigrade engine oils, hydraulic fluids, gear oils, transmission fluids, and industrial lubricants.
