Lubrizol 7067c Link
Because it is a PMA-based technology, Lubrizol 7067C exhibits better resistance to thermal breakdown than many hydrocarbon-based polymers. It does not readily form varnish or deposits when exposed to high-temperature hot spots inside a transmission or hydraulic system.
Why do formulators keep coming back to 7067C? Because it solves three major headaches in heavy-duty equipment:
1. Extreme Pressure (EP) Protection Hypoid gears and heavy-duty differentials create massive sliding friction. Without the right chemistry, the gear teeth will actually weld together and tear apart (scuffing). Lubrizol 7067C uses a carefully balanced sulfur-phosphorus system to create a sacrificial film on the metal surface, preventing seizure under high shock loads.
2. Thermal Stability Older gear oils would "cook" under high heat, leaving sludge and varnish behind. This additive package is formulated to withstand higher operating temperatures. It keeps differentials running cleaner, longer, even in hot climates or heavy towing scenarios.
3. Corrosion Control Water contamination is a fact of life in axles and gearboxes. Unlike some aggressive EP additives that can eat away at copper and bronze synchronizers, 7067C includes robust corrosion inhibitors to protect soft metals (bearings, bushings, synchronizers) while keeping the iron components rust-free.
Modern automatic transmissions require fluids that maintain a specific viscosity to actuate valves and clutch packs. Too thin (hot), and you get slip and wear. Too thick (cold), and you get shift lag. Lubrizol 7067C is widely used in OEM formulations for DEXRON and MERCON level fluids because of its shear stability and excellent low-temperature shifting performance.
Technical Product Report: LUBRIZOL® 7067C LUBRIZOL® 7067C is a high-performance, non-dispersant olefin copolymer (OCP) viscosity modifier primarily designed for use in multi-grade engine oils and various lubricant applications. It is engineered to maintain fluid performance and "stay-in-grade" reliability across a wide range of operating temperatures and conditions. 1. Key Performance Characteristics Versatile SAE Grading lubrizol 7067c
: Provides stay-in-grade performance for a wide range of SAE grades, specifically from 0W-16 to 20W-50 at recommended treat levels. High Thickening Efficiency
: Known for high thickening efficiency, which helps formulators achieve target viscosities with lower additive concentrations. Shear Stability : Offers an excellent Permanent Shear Stability Index (
) of approximately 25%, allowing for stable oil blends that resist mechanical breakdown. Solubility
: Features excellent solubility in both mineral and synthetic base oils, ensuring a stable and homogenous lubricant mixture. 2. Physical & Application Properties
: Typically supplied as solid pellet polymers, which eliminates the need for specialized equipment like guillotines or grinders during the handling process. Solubilization
: The pellets possess a high surface area for rapid solubilization. Blending is generally recommended at temperatures below 120°C Optional Formats Because it is a PMA-based technology, Lubrizol 7067C
: A liquid viscosity modifier (VM) concentrate version of 7067C is available upon request for manufacturers who prefer liquid handling. 3. Applications and Treat Rates LUBRIZOL® 7067C is used as a core additive component in: Multi-grade Engine Oils : Used at treat levels typically ranging from 0.12% to 1.44% by weight depending on the specific oil grade and base stock. Global Lubricants
: Suitable for use in global engine oil formulations where consistent performance is required across diverse geographic regions. 4.

Title: Unlocking High Performance: Why Lubrizol 7067C is a Game Changer for Driveline Lubricants
When you dive into the world of industrial additives, the numbers often blur together. Viscosity modifiers, detergents, dispersants—they all start to sound the same. But every once in a while, a specific product code stands out as an industry benchmark. Lubrizol 7067C is one of those codes.
If you are formulating gear oils or manual transmission fluids, you have likely seen this spec on a data sheet. But what makes this particular additive package so special? Let’s break down the chemistry and the performance. Title: Unlocking High Performance: Why Lubrizol 7067C is
Lubrizol 7067C is a concentrated, high-performance viscosity index improver (VII) and pour point depressant (PPD) additive package manufactured by the Lubrizol Corporation, a global leader in specialty chemicals. Specifically, it is a non-dispersant polymethacrylate (PMA) based additive.
Unlike dispersant modifiers that focus on suspending contaminants, the "non-dispersant" nature of Lubrizol 7067C makes it ideal for applications where sludge handling is not the primary requirement, but where precise viscosity control across a wide temperature range is critical.
While primarily industrial, some formulators use lower treat rates of 7067C to meet API GL-4 or GL-5 specifications for spiral bevel and hypoid axles. However, formulators must verify copper corrosion compatibility, as high treat rates can be aggressive to yellow metals (bronze, brass synchronizers).
Rating: 4.8/5 (Excellent for heavy-duty applications)
In the world of industrial lubricants and chemical manufacturing, the difference between a standard fluid and a high-performance one often comes down to a single component: the additive package. Among the pantheon of industrial additives, Lubrizol 7067C has carved out a reputation as a gold standard for specific, demanding applications. While not a household name, for engineers, procurement specialists, and formulators in the grease and oil industry, this alphanumeric code signifies reliability, extreme pressure protection, and formulation flexibility.
This article provides an in-depth, technical exploration of Lubrizol 7067C. We will cover its chemical composition, primary applications, performance benefits, handling protocols, and how it compares to alternative additives on the market.
