Viscosity Index Improver
Viscosity Index Improvers (VIIs) are polymers added to lubricants to improve their viscosity-temperature relationship. These additives help maintain the lubricant’s viscosity within the desired range over a wide temperature range, ensuring proper lubrication and protection under varying operating conditions.
Viscosity index improver (VII), also known as a viscosity modifier, is a crucial additive used in lubricant additive packages for engine oils, gear oils, and some hydraulic oils.

Function of Viscosity Index Improver:
Here’s an overview of the applications and benefits of Viscosity Index Improvers across various industries:
Viscosity Index Improver (VII) is a commonly used additive in lubricating oils, used to improve the viscosity characteristics of lubricating oils. The main purpose of this additive is to maintain a stable viscosity of the lubricant in an environment with changing temperatures, thus improving the performance and service life of the lubricant. Viscosity index improvers…
Viscosity index improver is an important additive mainly used to improve the rheological properties of polymers. In this article, we will introduce several common viscosity index improvers, including their working principles and characteristics, as well as comparisons with other similar products. Some examples of viscosity index improvers used in lubricants include: It is important to…
Viscosity index improver is an important additive mainly used to adjust and improve the viscosity index of liquids or gases. In rheology, the viscosity index is used to measure the fluidity of a substance under shear. The higher the viscosity index, the less fluid the material is under shear, and vice versa. Viscosity index improvers,…
A Viscosity Index Improver (VII) is a key additive used in lubricants (especially multi-grade engine oils, gear oils, and hydraulic fluids) to reduce the rate of viscosity change with temperature—making oils perform consistently across a wide temperature range. 🔍 What Does a Viscosity Index Improver Do? VII molecules expand as temperature increases, counteracting the natural…
HSP engine oil viscosity index improver is a type of viscosity index improver that is added to engine oil to improve its viscosity-temperature characteristics. It is mainly composed of highly saturated polymers, which are polymers with a high degree of saturation and cross-linking. HSP viscosity index improvers can effectively improve the viscosity-temperature characteristics of engine…
EPM ethylene propylene rubber viscosity index improver is an ethylene copolymer rubber mainly composed of ethylene units and a small amount of propylene units. It has excellent oil resistance, heat resistance, ageing resistance, weather resistance, chemical corrosion resistance, ozone resistance and other properties. It is mainly used in the manufacture of heat-resisting and oil-resisting rubber…
HSP Engine Oil Viscosity Index Improver are synthetic oils that are designed to improve the viscosity index of engine oils. They help maintain the correct viscosity of engine oil to ensure that the engine is functioning at optimal level. These types of oils increase the viscosity of the oil so that it performs better at…
