In the demanding world of lubrication, shear stability is paramount. It refers to a lubricant's ability to maintain its viscosity and protective film integrity when subjected to mechanical stress. For applications requiring peak performance and extended equipment life, EPM (Ethylene-Propylene Copolymer) polymers, such as those supplied by NINGBO INNO PHARMCHEM CO.,LTD, are an exceptional choice.

EPM polymers, often identified by CAS numbers like 9010-79-1, are specifically engineered to address the challenges of high-shear environments. Unlike less robust viscosity modifiers, EPMs possess a molecular structure that is highly resistant to mechanical breakdown. This means that as engines and machinery operate under intense conditions, the EPM within the lubricant continues to perform its function, ensuring consistent protection.

The benefit of this high shear stability is multifaceted. Firstly, it directly contributes to the longevity of the lubricant itself. A lubricant that maintains its viscosity for longer periods requires less frequent replacement, leading to reduced maintenance costs and downtime. Secondly, and perhaps more critically, it ensures the continuous protection of critical engine components. By preventing viscosity loss, EPMs help maintain optimal oil film thickness, reducing friction and wear, especially in high-performance engines.

NINGBO INNO PHARMCHEM CO.,LTD, as a leading manufacturer in China, is dedicated to producing EPM polymers with precisely controlled molecular characteristics to maximize this shear stability. Our Ethylene-Propylene Copolymer products are formulated to meet the stringent requirements of modern lubricant formulations. We understand that our customers rely on the consistent performance of our additives to deliver superior end-products.

The advantages of EPM polymers extend beyond shear stability. Their excellent low-temperature properties also contribute to reliable cold-start performance, a critical factor in reducing wear during the initial moments of operation. The high thickening ability of EPMs also offers formulation benefits, potentially reducing the overall additive treat rate needed to achieve target viscosity grades.

For lubricant formulators, partnering with a reliable supplier like NINGBO INNO PHARMCHEM CO.,LTD means gaining access to top-tier EPM polymers. By integrating these high-performance additives, you can confidently deliver lubricants that excel in demanding applications, offering superior protection and extended service life.
