Effect of biopolymer dose on viscosity in different carbon black type slurries

Laboratory work to define optimum dispersant dosage of biopolymers in carbon black stable slurries.

Measurements of Brookfield viscosity demonstrates the effect of varying dosages of our biopolymer on stable dispersions.

Key takeaways:

• High structure carbon blacks with high surface area require much higher dispersant dosages than low structure carbon blacks.
• Optimum dosages can significantly reduce viscosity.
• Reduced milling times and higher loading both serve to lower manufacturing costs.
