lubricants. This makes it an ideal "universal" modifier for manufacturers looking to simplify their additive inventory. IMCD Norway 2. Solubility and Blending The polymer exhibits excellent solubility

The solid polymer requires mechanical shredding or chopping to increase surface area before being added to preheated base oil.

: It is recommended to mix the VM into at least 75% of the total base oil charge before adding other performance additives to avoid compatibility issues. Why It’s "Interesting" for Formulators

Available as a solid polymer or as a liquid concentrate (e.g., Lubrizol 7077D Functional Products Performance Review 1. Versatility and Grade Coverage lubrizol 7067c

Lubrizol 7067C is a shear-stable, non-dispersant olefin copolymer (OCP) viscosity modifier. It is designed to be highly versatile, making it suitable for a broad range of passenger car motor oils (PCMO), heavy-duty diesel engine oils, and industrial lubricant applications.

Particularly in fuel-efficient and hybrid engine lubricants.

The product behaves as a high-molecular-weight hydrocarbon polymer. It relies on a balanced ethylene-propylene co-monomer ratio. This structure ensures optimal crystal-free low-temperature fluidity and strong oil solubility. : Nondispersant Olefin Copolymer (OCP) Physical Form : Solid polymer pellets or crumb Commodity Code : 39023000 (Propylene Copolymers) lubricants

: Full solubilization typically takes 2 to 3 hours with consistent agitation.

For those of us blending lubricants, 7067C is a workhorse. It offers excellent treat rates (usually between 5.0% and 7.5% depending on the base oil viscosity). It is forgiving with Group I, II, and III base stocks. And most importantly, it passes the rig tests without breaking a sweat. Versatility and Grade Coverage Lubrizol 7067C is a

In standardized testing (like the FZG scuffing load stage test and Timken OK Load test), formulations containing 7067C routinely exceed the performance of generic sulfurized additives. It achieves high load-carrying capacity without relying on aggressive, corrosive chemistry.

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.

The plot below illustrates how a base oil containing a Viscosity Index Improver (VII) like LUBRIZOL® 7067C maintains stable viscosity over a wide operating temperature range compared to standard unadditized oil.
