What are High-Shear Thickening Agents?
High-shear thickening agents are additives specifically designed to increase the viscosity of liquids under high shear rates. They significantly enhance the fluid's viscosity under high shear conditions, optimizing the rheological properties and processing performance of the product.
Mechanism of Action
These thickening agents work by forming strong network structures or cross-linked polymer chains within the liquid, increasing viscosity at high shear rates. They effectively boost the fluid's viscosity while maintaining stability and flowability under high shear conditions.
Characteristics and Advantages
- Efficient Thickening: Significantly increases viscosity under high shear rates, improving rheological properties and processing performance.
- Excellent Stability: Maintains stable thickening effects under high shear conditions, resistant to shear degradation.
