By utilizing solid polymers like 7067C, manufacturers gain flexibility in base oil selection—including Group II and Group III base stocks—and can reduce shipping costs associated with pre-blended liquid concentrates. Conclusion
Always filter samples to ensure no undissolved polymer remains, ensuring a high-quality finished lubricant. Performance in Motor Oils
Verdict: 7067C is superior to cheap S-P additives for long-life applications; cleaner than ZDDP for gearboxes with copper components.
Traditional lead-based or heavy metallic (zinc) additives leave particulate ash. Over time, this ash accumulates in filters, servo valves, and tight clearances. Because 7067C is , it burns off cleanly during thermal stress, keeping hydraulic and lubrication circuits pristine. This is critical for CNC machinery and precision gearboxes. lubrizol 7067c
One of the most interesting aspects of the 7067C story is its reliance on zinc.
Improving the temperature-viscosity relationship in various industrial fluids to prevent excessive thinning. Blending and Handling Guidelines
LUBRIZOL® 7067C belongs to the of solid/block olefin copolymer performance polymers. It acts as a rheology modifier by altering the lubricant's viscosity index (VI)—minimizing the rate at which oil thins at high operating temperatures while ensuring fluent circulation during cold startups. Specifications & Details Product Group / Principal LUBRIZOL® / Lubrizol Corporation Commodity Code 39023000 (Propylene-Ethylene Copolymers) Product Number Shear Stability Index (SSI) 25 SSI (ASTM D-6022 / Permanent Shear Stability Index) Physical Form By utilizing solid polymers like 7067C, manufacturers gain
Lubrizol 7067C was formulated specifically to ace this test. It provides the oxidative stability required to prevent sludge, ensuring that filters don't clog and valves don't stick. In the industry, passing HF-0 is the equivalent of a "Master Class" certification, and 7067C provides the chemical blueprint for that success.
High-shear mechanical agitation or localized recirculation loops drastically reduce dissolution times, shifting the solid polymer into a uniform, clear liquid concentrate. 6. Regulatory and Sourcing Context
: Full solubilization typically takes 2 to 3 hours with consistent agitation. This is critical for CNC machinery and precision gearboxes
Its versatility makes it suitable for customized applications. Performance Benefits
belongs to the latter category. It is not a consumer brand name you will see on a bottle at an auto parts store. Instead, it is a foundational chemical package used by blenders and formulators to create hydraulic fluids that are as durable as they are efficient. To understand 7067C is to understand the delicate chemistry of balance: protecting metal from itself while navigating an increasingly strict regulatory landscape.
Exceptional solubility in both Group I–III mineral oils and Group IV synthetic base stocks (PAO)
The primary benefits of incorporating Lubrizol 7067C into a formulation are:
: The pelletized form eliminates the need for specialized grinding equipment (guillotines or grinders), allowing for rapid solubilization and reduced blending times at temperatures below Application in Research
