| Product Overview
This product is formulated from high‑quality ethylene–propylene rubber using advanced manufacturing processes. It exhibits excellent shear stability, along with superior thickening performance, thermal stability, and a notable ability to enhance the viscosity‑temperature characteristics of lubricants, making it an exceptionally effective viscosity index improver.
| Product Advantages
1. Outstanding thickening performance: even a small dosage can deliver optimal thickening, thereby enhancing cost-effectiveness.
2. It exhibits excellent shear stability, with an SSI value below 20, thereby ensuring the engine’s long-term operational requirements.
3. It exhibits superior viscosity‑temperature characteristics, maintaining stable viscosity across a wide range of temperatures.
4. It exhibits superior high-temperature, high-shear viscosity, thereby meeting the engine’s lubrication requirements under high-temperature conditions.
5. It exhibits excellent low-temperature start-up performance and high-temperature cleaning performance, maintaining superior functionality under a wide range of extreme conditions.
6. It exhibits superior thermal oxidation stability, maintaining consistent performance under high-temperature conditions and extending service life.
| Product Applications
Viscosity index improvers are key additives used in the formulation of multigrade internal‑combustion engine oils, hydraulic fluids, and gear oils. By incorporating viscosity index improvers into lubricants, it is possible to produce multigrade oils that deliver excellent low‑temperature start‑up performance while maintaining appropriate viscosity at elevated temperatures, thereby enhancing lubricant performance, elevating product grade, extending service life, and enabling year‑round use.
| Usage ReferenceWhen formulating oils, the recommended dosage of this product is 1%–10%.
