For procurement managers and R&D scientists in the chemical industry, selecting the right performance additives is paramount to product success. Ethylene-Propylene Copolymer (CAS 9010-79-1) stands out as a versatile and highly effective component, particularly in the formulation of advanced lubricants and industrial fluids. Understanding its grades and applications is key to making an informed purchase decision. As NINGBO INNO PHARMCHEM CO.,LTD., a trusted manufacturer and supplier, we aim to provide clarity for those looking to buy this essential chemical.

Ethylene-Propylene Copolymer, often referred to as EPM or EPR, is a synthetic polymer known for its excellent chemical resistance, thermal stability, and unique rheological properties. Its primary function in lubricants is as a viscosity index (VI) improver. This means it helps maintain a more stable viscosity across a wide range of temperatures, preventing lubricants from becoming too thin at high temperatures or too thick at low temperatures. This property is critical for the longevity and performance of engines and machinery, especially under demanding operating conditions.

The referenced material highlights several grades of Ethylene-Propylene Copolymer, such as J-0010, J-0030, J-0043, and J-0050. Each grade is tailored for specific performance requirements:

  • J-0010: Characterized by low molecular weight, excellent solubility, and superior shear stability and low-temperature performance. It's ideal for modulating high-grade lubricants for CF-4 and above specifications.
  • J-0030: Offers strong thickening ability combined with better shear stability, suitable for high-grade lubricant modulation.
  • J-0050: Features strong thickening ability and good shear stability, making it effective for high-grade lubricating oil and single-stage oil thickening.
  • J-0043: Demonstrates excellent thickening performance, best suited for modulating low-grade lubricating oils and single-stage oil-glued industrial oils.

When sourcing this material, buyers often search for terms like 'buy ethylene propylene copolymer online' or 'ethylene propylene copolymer supplier China'. Recognizing these procurement needs, NINGBO INNO PHARMCHEM CO.,LTD. ensures a stable supply chain and competitive pricing. Our expertise as a manufacturer allows us to guarantee the quality and consistency of our products, meeting stringent industry standards.

Beyond lubricants, Ethylene-Propylene Copolymer finds applications as a processing aid in polymer production, enhancing extrusion and molding processes for materials like PVC. It also serves as an additive in coatings and inks, contributing to gloss and scratch resistance. For those seeking to improve their product formulations, understanding the specific properties of each grade and consulting with a reliable manufacturer is crucial. If you are looking to purchase Ethylene-Propylene Copolymer, consider the various grades available and how they align with your application needs. Enquire about pricing and availability to ensure you secure a high-quality, cost-effective solution for your business.
