Viscosity Intex Impeover Plant
At Liuminex, we specialize in the design, engineering, and turnkey execution of Viscosity Index Improver (VII) Plants—an essential installation in the production of high-performance lubricants and oils. Our systems are built with precision and innovation to support the growing global demand for advanced lubricant formulations that perform consistently across a broad temperature range.
Viscosity Index Improvers are critical polymer additives used in lubricants to enhance their viscosity-temperature behavior. Our VII plants are engineered to deliver the highest quality products while optimizing operational efficiency, environmental safety, and long-term reliability.
What Is a Viscosity Index Improver?
A Viscosity Index Improver (VII) is a polymer-based additive used in the formulation of multigrade engine oils and industrial lubricants. It helps maintain the lubricant’s viscosity over varying temperatures, ensuring stable and effective lubrication during cold starts and at high operating temperatures.
VII compounds, such as olefin copolymers (OCP), polymethacrylates (PMA), and hydrogenated styrene-diene copolymers (HSD), are typically synthesized and blended in specialized process units. These compounds enhance the performance of engine oils by preventing excessive thinning at high temperatures and thickening at low temperatures.
Our Expertise in VII Plant Engineering
We offer complete end-to-end solutions for the development of Viscosity Index Improver manufacturing plants, including:
