![]() ![]() Viscosity index improvers (VIIs) are added to lubricants to prevent motor oil / lubricant from evaporating. The viscosity of lubricating oil is the most important factor that influences its consumption. When an engine oil / lubricant added to an automobile engine is exposed to extreme temperature swings, typically between 40 and 100 degrees Celsius, it begins to thin, which can cause the engine oil / lubricant to evaporate, causing damage or knocking out of the engine due to high friction between internal engine parts. Automobile lubricants serve four purposes: they control engine friction and wear, protect the engine from rust, cool the pistons, and protect the engine oil in the sump from combustion gases. While driving, the temperature of the automobile's engines changes dramatically. The automotive industry is the largest consumer of lubricants. To know about the Research Methodology :- Request Free Sample Report Viscosity Index Improvers Market Dynamics: Despite a shift toward shared transportation, which increased demand for lubricants following the COVID-19 pandemic, vehicle unit sales will continue to rise: As a result, mineral oils' lubricating properties can be extended over a larger temperature range. When low-viscosity oils are thickened with viscosity index improvers, the oil thickens as the temperature rises. Viscosity improvers also make it possible to make multigrade oils, eliminating the requirement for seasonal oil changes. This guarantees that the lubricant provides complete protection to the equipment at both high and low temperatures. The interactions decrease as the temperature rises, compensating for the loss of viscosity. ![]() The interactions between molecular chains are significant at low temperatures. Also, high molecular polymers with a flexible primary molecular chain are viscosity index improvers. A viscosity index improver is a complex polymer addition that thickens the lubricant and ensures a more stable and consistent viscosity at high temperatures. Polymers used in a lubricant to make it resistant to changes in viscosity as the temperature rises are known as viscosity index improvers. If a lubricant's viscosity changes dramatically at different temperatures, it is said to have a low viscosity index. Also, the viscosity index indicates a liquid's sensitivity to temperature changes. Viscosity Index Improvers Market Overview:Ī liquid's viscosity is defined as its inherent resistance to flow. The report analyzes Viscosity Index Improvers market dynamics by region, type, and end-users. Viscosity Index Improvers Market is expected to reach US $5.4 Billion by 2029, thanks to growth in the Olefin Copolymer segment.
