A viscosity index improver is a complex polymer additive that grows at high temperatures, thickening the lubricant and more stable and consistent viscosity. It ensures that the lubricant protects the equipment completely at low and high temperatures. Viscosity Index (VI) improvers are chemical compounds typically added to lubricants to prevent thinking, i.e. decrease in viscosity of the lubricant with increasing temperature and ensure consistent performance at varying temperatures. Viscosity Index improvers are polymeric molecules that grow as the temperature rises. The internal friction between fluid molecules increases as the molecules stretch out, causing the fluid to flow slower and ultimately increasing the viscosity.

Viscosity Index Improvers Market size was accounted for USD 3,451.4 Million in 2020 and expected to reach USD 4,552.9 Million by 2028.

Viscosity Index Improvers Market Dynamics

Increasing Focus on Improving Pollution index and Fuel Efficiency

The increasing focus of automakers worldwide on reducing carbon footprints and improving fuel efficiency is expected to drive demand for Viscosity Index Improvers. It will boost the production of high-quality lubricants like crankcase oil and gear lubes. Lubricants are used to reduce friction between two moving parts by introducing a thin film to avoid direct contact with the moving parts and reduce friction losses as the life of the parts increases.

In North America, the U.S. and Canadian countries are accounted for USD 607.12 Million and USD 54.41 Million in 2020, with a CAGR of 3.6% and 2.8 % during the forecast period of 2020-2028, respectively. Although due to the contact of moving parts, especially at high speeds, the temperature increases, which increases the temperature of the lubricant introduced between them and causes the lubricant to be thin, which can lead to evaporation of the lubricant or reduced performance. To ensure that the lubricant remains effective even at higher temperatures, various additives, including viscosity index improvers, are added to increase the consistency and effectiveness of the lubricant at various temperatures. 

Lubricants are used extensively in automotive and industrial applications, and the quality of the lubricant determines the lifespan of the mechanical components used in the industry. Because of the large capital investments, companies make in this continuous-operation machinery, preventive measures, corrective maintenance, and breakdown maintenance are required.

Increasing Costs in Production Process and Technology

Viscosity index improver (VII) is a lubricant additive used to increase the viscosity index of petroleum-derived lubricants. Viscosity index improver can reduce emissions, save energy, and strengthen the protection of various mechanisms. Although the global market share of the Viscosity index improver is still relatively high, it has suffered from overcapacity in recent years, drawing attention to the Viscosity index improver industry's development potential. Many companies are attempting to increase the demand for Viscosity index improver products in engine oil by promoting their application orientation.

Rising costs in the production process and technology, rising costs in raw materials, rising competition in mature markets, environmental requirements regarding emissions, increasing difficulty in protecting patents, and rising price pressure due to low growth rates in mature markets were the rising constraints to demand.

Long Engine Oil Drain Intervals

Over the last few years, ongoing technological advancements in the automotive industry have resulted in the evolution of engine technology and lubricant oil chemistry. The advancement has increased the engine oil drain interval for heavy-duty trucks from an average of 25,000 miles to as much as 50,000 miles. Furthermore, the increased use of cleaner fuels, superior lubricants, dependable engines, and superior filter technology has increased the average oil drain interval. This increase in the oil drain interval will reduce engine oil consumption in automobiles, and it is expected to limit demand for viscosity index improvers over the forecast period.

Lack of Strong Substitute

There are several applications for viscosity index improvers on the market that any other base oil cannot replace. And in most cases, there is no industry option to replace viscosity index Improver additives due to the impossibility of finding substitutes that work equally well or meet all quality specifications at a competitive price. As a result, the demand for viscosity index improvers is increasing in various fields because they are used in almost every aspect of the oil and gas industry, particularly in the petroleum processing and refinery segments.

It has been noted that there are currently no high-quality synthetic alternatives available on the market that provide comparable performance benefits in terms of stabilizing oils against hydrogen degradation and protection against wear.

Functions of Viscosity Index Improvers

An oil-soluble chain polymer with a weight-average molecular weight ranging from 10000 to 500000 is the main component of Viscosity Index Improvers. It works by causing changes in the dissolved state of oil-soluble polymers in lubricating oils.

At high temperatures, the polymer's solubility in lubricating oil is high, and the molecular chains spread, causing the viscosity of the lubricating oil to increase significantly. However, at low temperatures, the polymer's solubility is low, and the molecular chains become coiled, limiting the viscosity of the lubricating oil's increase. In short, one of VII's functions is to keep the viscosity of lubricating oil within a reasonable range.
