A viscosity index improver is a complex polymer addition that increases at high temperatures, thickening the lubricant and creating a more stable and consistent viscosity. It guarantees that the lubricant protects the equipment completely at low and high temperatures. Viscosity Index (VI) improvers are chemical compounds commonly added to lubricants to avoid thinking, i.e., reduction in viscosity of the lubricant with increasing temperature and provide constant performance at varied temperatures. Viscosity index improvers are polymeric molecules that expand as the temperature rises. The internal friction between fluid molecules rises as the molecules stretch out, causing the fluid to flow slower and ultimately raising the viscosity.

The intrinsic reluctance of a liquid to flow is referred to as the liquid's viscosity. In addition, the viscosity index describes how a liquid reacts when its temperature is changed (often between 40 and 100 degrees Celsius). If a lubricant has a significant shift in its viscosity when subjected to a range of temperatures, then we classify it as having a low viscosity index. Viscosity index improvers are polymers that are combined with a lubricant in order to produce a substance that is resistant to changes in its viscosity as a result of an increase in temperature.

On the worldwide market for viscosity index improvers, some of the most important product types that are now accessible are polyisobutylene, polymethacrylate, and olefin copolymer. In addition to this, their goods are being utilised in a wide variety of end-use sectors, including the off-road vehicle business, the industrial machinery industry, and the automobile industry. Because of the product's widespread applicability, there are now a number of interesting business prospects available in the market for viscosity index improvers.

Lubricants are compounds that are used to reduce the amount of friction that exists between two surfaces. As a result, lubricants give wear protection to surfaces and increase the operating efficiency of a system. As a result, lubricants contribute to longer runtimes for machines and prevent the wear and tear that occurs on machine parts. Viscosity index improvers are becoming increasingly popular since they are an essential component of each batch of lubricant additives. This is due to the fact that they have the capacity to assist in the preservation of viscosity even when lubricants are subjected to high operating temperatures. As a result, it is anticipated that an increase in the use of lubricants will drive demand channels in the market for viscosity index improvers in the years to come.

The rate of urbanisation is increasing in a number of emerging nations, including those that make up the BRICS. Because of this feature, the worldwide market for viscosity index improvers is seeing significant prospects for expansion.
