Improving the temperature-viscosity relationship in various industrial fluids to prevent excessive thinning. Blending and Handling Guidelines
Lubrizol 7067C serves as an effective for greases and biodegradable fluids. Unlike conventional tackifiers (such as PIBs) that may have limited solubility in esters and bio‑fluids, Lubrizol 7067C readily dissolves at up to 4% in most esters and bio‑fluids . This property makes it particularly valuable for formulating:

One of the most critical requirements for modern engine oil is the ability to maintain its viscosity under high-shear conditions (e.g., inside an engine). Lubrizol 7067C is designed to offer excellent shear stability, as indicated by its PSSI (Permanent Shear Stability Index). This ensures that the lubricant does not "thin out" prematurely, protecting engines during long drain intervals. 2. High Thickening Efficiency lubrizol 7067c
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.

This additive is not a "universal" fix-all, but it is the gold standard for specific, demanding applications.
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. it helps prevent engine wear.
Because it is compatible with a wide range of base oils and helps meet various SAE specifications, it is often treated as a "universal" component for global engine oil formulations.
It is important to distinguish between the and fluids containing the additive . Many lubricant blenders will advertise that their oil is "Formulated with Lubrizol 7067C." Here is how it stacks up:
Lubricant formulators rely on this component to bridge the gap between low-temperature engine startup and high-temperature high-shear (HTHS) conditions. Core Technical Profile
The formulation is tested to ensure it does not cause excessive swelling or shrinkage of elastomer seals commonly found in engines. demanding applications. Beyond PMA technology
