Product Introduction
J0050 Ethylene Propylene Copolymer is a high-performance EPDM viscosity modifier engineered for extreme shear stability and thermal endurance. With a molecular weight of ~100,000 g/mol and narrow molecular distribution, it delivers superior thickening efficiency and permanent viscosity loss control. Key applications include heavy-duty engine oils, high-pressure hydraulic systems, and wind turbine gear oils operating under severe mechanical stress.
Advanced Features
- Shear Stability Excellence
SSI(40-45): Maintains viscosity within 5% after 30 cycles in Bosch injector shear tests.
- Thermal Resilience
Withstands 160°C continuous operation (ΔKV100 <3% after 1,000h ASTM D445).
- Low-Temperature Performance
MRV TP-1 ≤25,000 cP @ -40°C (ASTM D4684): Ensures cold-start pumpability.
- High Thickening Efficiency
40% higher VI boost vs. standard OCPs (7.0 cSt thickening per 1% treat rate in 150N base oil).
- Emission Compatibility
Zero phosphorus/sulfur; compatible with Euro VII/China VI-B aftertreatment systems.
