Information

Viscosity Index Improver VII is an oil-soluble high molecular polymer, in the form of rubber or solid at room temperature, and its molecular weight ranges from tens of thousands to hundreds of thousands. When the high molecular polymer is dissolved in the lubricating oil, it forms a coil structure, and the viscosity of the oil is much greater than that of the solvent to thicken. At low temperature, the high molecular polymer exists in the form of a coil, which has little effect on the viscosity of the oil; as the temperature increases, the coil stretches and the effective volume increases, which increases the viscosity of the oil significantly. VII is based on having different forms at different temperatures and having different effects on viscosity to increase oil viscosity and improve viscosity-temperature performance.

Cheapest Viscosity Index Improver

The thickening ability of VII determines the amount of VII added in the multistage engine oil. The greater the thickening ability of VII, the smaller the amount added, the lower the cost of the multistage oil, and the less impact on the detergency of the multistage engine oil.
