7067c - Lubrizol

If your application requires a fluid that flows like a winter-grade oil at -40°C yet protects like a summer-grade oil at 100°C, without losing its viscosity profile after 5,000 hours of operation, Lubrizol 7067C is the industry benchmark you need. Disclaimer: This article is for informational purposes only. While every effort has been made to ensure accuracy, specific formulation results vary based on base oil quality, blend temperature, and the presence of other additives. Always consult the official Lubrizol technical data sheet (TDS) and Safety Data Sheet (SDS) before industrial use.

For blenders targeting the ATF, high-performance hydraulic, or industrial gear markets, incorporating Lubrizol 7067C signals a commitment to quality. For end-users, understanding that an oil contains a PMA-based, non-dispersant modifier like 7067C tells you that the lubricant is engineered for thermal stability and mechanical longevity.

If you are involved in the production of automatic transmission fluids (ATFs), hydraulic fluids, or industrial gear oils, you have likely encountered this specification. But what exactly is Lubrizol 7067C, and why has it become a benchmark for shear stability and viscosity control? lubrizol 7067c

Do not mix Lubrizol 7067C with sulfurized extreme pressure (EP) additives at temperatures exceeding 90°C for prolonged periods without proper antioxidant balancing. The high reactivity of EP chemistry can sometimes neutralize the polymer's effectiveness. Lubrizol 7067C vs. Competitors (Additives & OEM Fluids) It is important to distinguish between the additive itself and fluids containing the additive . Many lubricant blenders will advertise that their oil is "Formulated with Lubrizol 7067C." Here is how it stacks up:

| Feature | Lubrizol 7067C | Standard OCP Modifiers | High-Molecular Weight PAO | | :--- | :--- | :--- | :--- | | | Excellent (Low) | Poor (High) | Good | | Low Temp Viscosity | Excellent | Poor | Excellent | | Cost | Medium/High | Low | Very High | | Thickening Efficiency | Medium | High | Medium | | Best Use Case | ATF, Hydraulics | Motor Oils | Compressors, Low Temp | If your application requires a fluid that flows

Lubrizol 7067C consists of long, coiled polymer chains. At low temperatures (cold starts), these chains remain tightly coiled, contributing little to the fluid's internal resistance. As the temperature rises, the polymer chains expand and uncoil. This expansion pushes against the flow of the oil, counteracting the natural thinning effect of the base fluid.

In the world of industrial lubricants and specialty chemicals, the difference between adequate performance and exceptional efficiency often comes down to a single additive. One such critical component that has garnered significant attention among formulators and engineers is Lubrizol 7067C . Always consult the official Lubrizol technical data sheet

This article provides an in-depth analysis of Lubrizol 7067C, covering its chemical composition, technical benefits, application ranges, and how it compares to alternative additive technologies. 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.
