China Viscosity Index Improver Suppliers
Viscosity Index Improver (VII) is one important Lube Additive that helps to control the viscosity of lubricants under different temperatures, It improves the viscosity-temperature performance of the lube oil.
An ideal Viscosity Index Improver should have the ability to improve the engine oil's performance:
- Shear Stability;
- Thickening Ability;
- Thermal/Oxidative Stability;
- Low-Temperature Performance;
- High temperature, high shear rate (HTHS).
Common Viscosity Improvers include (Polyisobutylene) PIB, (Olefin Copolymer based Viscosity Index Improvers)OCP , (Polymethacrylate)PMA, (Hydrogenated styrene diene copolymer )HSD.
FAQ About Viscosity Modifiers
What is viscosity index improver
Viscosity index improvers are oil-soluble polymer compounds that can increase the viscosity and viscosity index of oil and improve the viscosity-temperature properties.
Why should we add Viscosity Improvers in the engine oil?
They are important additives in engine oil used to formula multi-grade engine oil, hydraulic oil, and gear oil. VIIs improve the performance of lubricants by providing good low-temperature performance and maintaining appropriate viscosity at high temperature, They improve the grade of lubricating oil, extend the service life of lubricating oil, and make the oil suitable for all seasons.
Advantages and disadvantages of various Viscosity Index Improvers?
Each viscosity Index Improvers has its advantages and disadvantages, generally， we evaluate its performance from Thicken Ability Viscosity Index Improve ability, Shear Stability, Decrease Pour Point, Low Temperature performance, High Temperature Shear Viscosity, Oxidation Stability.
