: Highly efficient at increasing viscosity even at low treat levels, which can assist in optimizing formulation costs. Key Advantages Broad SAE Grade Coverage
It acts as the "salt and pepper" for the base oil. A blender takes Group I or Group II mineral oils (the base liquid), adds a specific percentage of 7067C (usually around 0.8% to 1.0% by weight), and the result is a premium hydraulic fluid capable of extending the life of equipment by thousands of hours. The information provided herein is for and does
Typical treat levels (by weight percentage) vary based on the specific SAE grade being formulated: : 0.75% – 1.12% SAE 10W-40 : 1.0% – 1.37% SAE 20W-50 : 0.66% – 0.87% Formulation and Handling
Used to create multigrade lubricants spanning 0W-16 to 20W-50, ensuring proper viscosity in both winter and summer conditions. Key Advantages Broad SAE Grade Coverage It acts
: Evaluating how VII polymers affect the Cold Cranking Simulator (CCS) and High-Temperature High-Shear (HTHS) viscosity of a lubricant. Energy Efficiency
Unlike standard modifiers, the 7067C is noted for its . This means a single additive can be used to meet different international standards, simplifying the supply chain for companies that distribute engine oils in multiple countries.
