These characteristics make it suitable for lithium complex greases, calcium sulfonate greases, and other high‑performance grease types.
Lubrizol 7067C is a solid, pelletized ethylene-propylene copolymer. Unlike liquid viscosity improvers that require complex blending procedures, the pellet form of 7067C is designed for ease of handling and faster dissolution into base oils. It belongs to the class of olefin copolymers (OCPs), which are favored in the lubricants industry for their excellent thickening efficiency and cost-effectiveness. Chemical Composition and Form Ethylene-Propylene Copolymer (OCP). Appearance: Solid Pellets.
Zinc-based additives like 7067C offer a superior "load-carrying" capacity at a lower cost compared to many ashless alternatives. For heavy-duty industrial machinery—steel mills, injection molding machines, and mobile construction equipment—the wear protection provided by the zinc in 7067C is often seen as indispensable. It represents the "sweet spot" where maximum protection meets reasonable cost. : It is versatile enough to provide stay-in-grade
Complete solubilization is typically achieved within 2 to 4 hours when mixed in base oil at temperatures between 120°C and 130°C .
Beyond PMA technology, Lubrizol 7067C also incorporates hydrogenated polyisoprene star polymers. This advanced molecular architecture enhances the additive's overall stability and thickening efficiency, allowing it to contribute to the lubricant's structural integrity under variable temperatures and shear forces.

Lubrizol 7067C is a chemical product and should be handled with appropriate care. The following general safety precautions apply:
Lubrizol 7067C is highly regarded for its unique balance of properties, offering several key advantages in oil formulation: 1. High Thickening Efficiency
Because the physical property data (such as density, flash point, viscosity, and pour point of the concentrate) are proprietary to Lubrizol and not widely published in open literature, users should obtain the official Technical Data Sheet (TDS) and Safety Data Sheet (SDS) directly from The Lubrizol Corporation. ЭКОЛОГИЯ
: Its use in ultra-low viscosity grades like 0W-16 highlights its role in modern fuel economy standards. Shear Stability Analysis
Blending is generally recommended at temperatures between 120°C and 130°C (248°F - 266°F) to ensure complete solubilization.
