Ethylene Diene Monomer/EPDM
Ethylene Diene Monomer (EPDM) rubber stands out as a critical component in modern lubricant formulations, primarily for its exceptional ability to act as a Viscosity Index Improver (VII). This terpolymer of ethylene, propylene, and a non-conjugated diolefin offers remarkable resistance to harsh conditions such as oxidation, ozone, and erosion, making it ideal for applications demanding durability and consistent performance. Its low specific gravity allows for significant filler and oil absorption without compromising its inherent characteristics, leading to cost-effective yet high-performing lubricant compounds. The intrinsic properties of EPDM make it a cornerstone for formulators aiming to achieve superior lubrication under extreme temperature variations.
- Leverage EPDM's superior oxidation, ozone, and erosion resistance to boost the longevity of your lubricants.
- Achieve excellent shear stability and thermal oxidation stability, crucial for demanding industrial applications.
- Experience improved low-temperature properties, ensuring reliable performance even in freezing conditions.
- Benefit from EPDM's excellent compatibility with other functional additives and pour point depressants for tailored formulations.
Advantages of EPDM
Enhanced Viscosity Stability
EPDM polymers effectively improve the viscosity index (VI) of lubricants, ensuring a more stable viscosity across a wide temperature range, crucial for maintaining oil film thickness and wear protection.
Superior Durability
With excellent resistance to weathering and outdoor aging, EPDM ensures that lubricants maintain their integrity and performance under challenging environmental conditions.
Cost-Effective Formulations
The high thickening efficiency of EPDM allows for reduced treatment rates, leading to potential cost savings in lubricant formulations while maintaining high performance.
Key Applications
Industrial Lubricants
EPDM acts as a crucial viscosity modifier in industrial lubricants, enhancing their performance in heavy machinery and extreme operating environments.
Engine Oils
By improving the viscosity index, EPDM contributes to better engine protection and fuel economy in both passenger car motor oils and heavy-duty engine oils.
Greases
EPDM's thickening capabilities make it an excellent component for high-performance greases, ensuring consistent lubrication under pressure and temperature.
Gear Oils
For gear oils, EPDM helps maintain optimal viscosity and shear stability, critical for protecting gears in transmissions and other heavy-duty applications.
