Lubrizol 7067c

Unlike some high-molecular-weight polymers that trap air (leading to foaming, cavitation, and slow hydraulic response), Lubrizol 7067C, when formulated correctly, maintains good air release properties. This is vital for hydraulic systems operating at high cycles per minute.

Lubrizol 7067C is a vital building block in modern lubricant chemistry. Its advanced dispersancy technology enables engine oils to handle higher levels of soot and contaminants introduced by modern emissions control systems. By preventing sludge, controlling viscosity increase, and protecting engine surfaces, it plays a critical role in extending engine life and oil drain intervals.

According to documentation from IMCD United States and IMCD Lithuania, the product falls under the following classifications: Product Group: Additive component / Lubricant additive. Commodity Code: 39023000.

Physical Form: Typically supplied as a solid polymer, though a liquid concentrate version is available upon request. Handling and Blending lubrizol 7067c

For optimal results, it is recommended to shred the solid polymer and solubilize it in oil at temperatures between 120°C and 130°C. This process generally takes 2–3 hours with conventional mixing equipment. In-house solubilization is often preferred by formulators to reduce costs and increase flexibility in base oil selection.

Lubrizol 7067C: The Engine Behind Modern High-Performance Lubricants Disclaimer: This report is based on general technical

In the world of automotive and industrial lubricants, maintaining the right consistency across extreme temperatures is a constant engineering challenge. Lubrizol 7067C is a high-performance viscosity modifier (VM) polymer designed to tackle this exact problem. This specialized additive belongs to the Lubrizol 7060 Series, a family of olefin copolymer (OCP) viscosity modifiers used globally to formulate engine oils that stay stable under stress. What is Lubrizol 7067C?

Lubrizol 7067C is a versatile polymer additive primarily used as a viscosity index improver. In simple terms, it helps oil maintain its "thickness" (viscosity) when hot, ensuring critical engine parts are protected, while still allowing the oil to flow freely when cold for easy starts. Product Group: Additive component / Lubricant additive. Chemical Nature: Olefin Copolymer (OCP).

Physical Form: Typically available as a solid pellet or a liquid concentrate version upon request. Key Features and Benefits

Engineered for "stay-in-grade" performance, Lubrizol 7067C offers several critical advantages for lubricant manufacturers:

High Thickening Efficiency: It provides significant viscosity increases at low treat rates, allowing for cost-effective formulations.

Excellent Solubility: It dissolves readily in both mineral and synthetic base oils, making it compatible with a wide range of global formulations.

Shear Stability: It is designed to resist mechanical "shearing"—the physical breakdown of polymer chains within an engine—ensuring the oil doesn't thin out prematurely over time.

Wide SAE Grade Coverage: This additive is suitable for a broad spectrum of oil grades, including modern fuel-efficient grades like SAE 0W-16 up to heavy-duty grades like SAE 20W-50. Core Applications

While its primary home is in the automotive sector, its versatility extends to various industrial uses:

Passenger Car Motor Oils (PCMO): Enhancing the performance of modern gasoline and diesel engines. For lubricant blenders, achieving a homogenous product is

Heavy-Duty Diesel Engine Oils: Providing the durability required for long-haul trucking and construction machinery.

Industrial Lubricants: Used in various industrial fluids where temperature-viscosity stability is paramount. Technical Handling and Blending

For manufacturers, Lubrizol 7067C is prized for its ease of use. If using the solid pellet form, it eliminates the need for expensive grinding equipment often required for larger polymer blocks.

Solubilization: Complete solubilization is typically achieved within 2 to 4 hours when mixed in base oil at temperatures between 120°C and 130°C.

Storage: Like most petroleum-based additives, it should be stored in a cool, dry place. For long-term storage, temperatures should generally be kept below 45°C to maintain product integrity. Why Choose Lubrizol 7067C?

In an era where automotive standards like API and ACEA are becoming increasingly stringent, Lubrizol 7067C offers a reliable foundation for meeting these global specs. Its ability to maintain fluid performance across varied operating conditions makes it a staple for formulators looking for a "workhorse" viscosity modifier that doesn't compromise on efficiency or solubility.

For lubricant blenders, achieving a homogenous product is straightforward but requires precision.

Standard Blending Procedure:

Important note: Do not blend 7067C directly with water or use in water-glycol hydraulic fluids. It is strictly an oil-soluble additive.

When incorporated into grease formulations, Lubrizol 7067C creates a "tacky" yet stable EP grease. This is vital for open gears, fifth wheels on trucks, and heavy construction equipment (excavators, bulldozers). The additive migrates to the metal surface, ensuring that even when the base grease is squeezed out under immense pressure, a protective chemical barrier remains.
