Understanding Lubrizol 7067C: A Highly Versatile Viscosity Modifier
Before purchasing, review this checklist:
The most common application is in heavy-duty industrial gear drives. Gearboxes in steel mills, cement plants, mining conveyors, and wind turbines operate under slow speed, high torque conditions. Here, lubricant films are easily penetrated, leading to micro-welding of gear teeth (scuffing). Lubrizol 7067C provides a sacrificial chemical layer that shears before the metal does, preventing adhesive wear. lubrizol 7067c
Lubrizol 7067C 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.

The following table summarizes the typical properties found in performance evaluations of Lubrizol 7067C (solid polymer form): Typical Value Appearance White transparent colloid/solid Composition Polymerized ethylene and propylene Kinematic Viscosity (100°C) ~9.14 - 9.59 mm²/s (depending on batch) Viscosity Index ~133 - 137 Shear Stability Index (SSI) 14.7% - 21.1% (30-cycle diesel injector) Pour Point -24°C to -32°C Applications in Lubrication
Important note: Do not blend 7067C directly with water or use in water-glycol hydraulic fluids. It is strictly an oil-soluble additive. viscosity modifier designed for use in a wide
viscosity modifier designed for use in a wide range of global engine oils and industrial lubricants. It is primarily recognized for its ability to maintain "stay-in-grade" performance across diverse SAE viscosity grades.
