The Role of Viscosity Index Improvers in Lubricating Oil
Viscosity index improvers are one of the indispensable additives in lubricating oil, especially suitable for multi-grade engine oil, hydraulic oil and industrial lubricating oil. Its main function is to maintain the stability of lubricating oil viscosity in high and low temperature environments, enhance the performance of lubricating oil in use and the protection capacity of equipment.
At low temperatures, VII molecules contract without affecting the fluidity of the oil. At high temperatures, its molecular chains stretch, effectively preventing the viscosity of the lubricating oil from dropping too rapidly and ensuring the lubrication performance of the engine under high-temperature conditions. This "intelligent responsive" feature makes it a core component of modern high-performance lubricants.
By choosing our viscosity index improver, the viscosity-temperature performance of lubricating oil can be enhanced, the oil change cycle can be extended, friction and wear can be reduced, and mechanical efficiency can be improved.
