Polymer VI Improver
High-Performance Viscosity Index Enhancer
Polymer VI Improver is a specialized polymer-based additive used in lubricants to enhance their viscosity index and deliver stable performance across a wide temperature range. As a polymer viscosity index improver, it strengthens oil viscosity at high temperatures while maintaining fluidity at low temperatures, ensuring optimal lubrication for automotive and industrial oils. This additive is essential for modern multigrade engine oils, hydraulic fluids, transmission oils, and other high-performance lubricants.
Why Choose Polymer VI Improver?
As a polymeric viscosity index enhancer, this additive modifies the rheological behavior of lubricants to deliver consistent performance under thermal stress. At low temperatures, the polymer chains remain compact to maintain oil flow, while at high temperatures they expand to maintain oil thickness. This dual action ensures long-lasting stability, improved engine protection, and enhanced oil durability.
- Polymer-based formula for effective viscosity index improvement
- Enhanced high-temperature viscosity retention
- Improved cold-start fluidity and flow
- Stronger film strength under load and thermal stress
- Reduced oil consumption and volatility
- Compatible with engine oils, hydraulic oils, and gear lubricants
Optimized Polymer Chemistry for Superior Performance
The polymeric VI improver structure enables the lubricant to maintain a balanced viscosity profile regardless of operating conditions. This performance advantage is critical for modern engines and equipment that operate under fluctuating temperatures and require stable lubrication at all times.
- Ideal for multigrade engine oil formulations
- Suitable for high-performance hydraulic and transmission fluids
- Improves thermal stability and resistance to viscosity breakdown
- Reduces friction by maintaining optimal oil thickness
- Supports extended oil drain intervals
By preventing viscosity collapse at high temperatures, Polymer VI Improver significantly enhances equipment protection and extends component life.
Cleaner Operation and Longer Oil Life
Polymer VI Improver works synergistically with detergent, dispersant, and anti-wear additive systems to deliver cleaner operation. By maintaining stable viscosity, it minimizes deposit formation, reduces oxidation stress, and ensures oils maintain their protective properties throughout service life.
