While it thickens well at high temperatures, it is engineered not to negatively impact cold-start performance, which is critical for 0W and 5W engine oil grades. Usage and Applications
The solid matrix dissolves most efficiently when blended into a base oil carrier at temperatures between 100°C and 120°C . Heating above 130°C should be avoided to prevent thermal-oxidative degradation of the polymer chains.
Why do formulators keep coming back to 7067C? Because it solves three major headaches in heavy-duty equipment:
Structurally, Lubrizol 7067C is polymerized from ethylene and propylene, creating a robust copolymer. It is typically supplied in solid, white transparent pellet form. This solid state makes it exceptionally easy to handle, transport, and store, and it eliminates the need for messy liquid handling in blending facilities. Key Performance Advantages lubrizol 7067c
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.
Used to create multigrade lubricants spanning 0W-16 to 20W-50, ensuring proper viscosity in both winter and summer conditions.
In the world of automotive and industrial lubricants, maintaining the right consistency across extreme temperatures is a constant engineering challenge. 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? While it thickens well at high temperatures, it
In the world of industrial and automotive lubrication, the performance of base oils alone is often insufficient to meet the demanding requirements of modern machinery. Additives are the key to unlocking the full potential of any lubricant, and one such key player is Lubrizol 7067C.
Optimizing Fluid Mechanics: An In-Depth Guide to Lubrizol 7067C Viscosity Modifier
: Before dropping the batch, draw fluid samples and run them through fine filter mesh screens to verify zero un-dissolved polymer "fish-eyes" remain. Why do formulators keep coming back to 7067C
: Because blending occurs at elevated temperatures, applying a nitrogen gas blanket (blanketing) is strongly recommended to eliminate oxygen and prevent oil discoloration or thermal oxidation.
). The dissolution time depends heavily on the blender's agitation efficiency and setup.
Lubrizol 7067C does not exist in a vacuum; it competes with other additives from Lubrizol and other manufacturers.
