Hydrogenated Styrene Isoprene Polymer Viscosity Index Improver Additives
Ultra-Stable VI Booster for Extreme-Temperature & Bio-Lubricant Formulations
Our premium viscosity index improver additives have the characteristics of low polymer content, good shear stability, excellent high and low temperature performance, and minimal deposits in internal combustion engines. These viscosity index improver additives can be used to prepare multi-grade internal combustion engine oil, hydraulic oil, gear oil, grease, and more.
Product Introduction
This Hydrogenated Styrene Isoprene Polymer (HSIP) leverages advanced catalytic hydrogenation technology to deliver unmatched viscosity-temperature performance. With 92.6% hydrogenation saturation of isoprene blocks13, it eliminates double-bond vulnerability while preserving aromatic stability, enabling >50,000-hour durability in bio-lubricants and extreme-temperature environments.
- Viscosity Index Superbooster™
Achieves VI >450 in Group III+/IV base oils (ASTM D2270).
- Shear Stability Mastery
<3% permanent viscosity loss after 100h KRL test (CEC L-45-A-99).
- Bio-Oxidation Resistance
5x extended life in ester-based bio-lubricants vs. conventional VIIs (ASTM D943 modified).
- Arctic Flow Enhancement
Maintains -60°C cold-cranking viscosity (ASTM D5293).
- Zero Deposit Guarantee
98% cleaner pistons in biodiesel engines (Sequence IIIH validated).
