Insoluble additives, or high concentrations of additives which are partly soluble are perfectly dispersed with the Sulzer Static Mixers. Normally these additives are of very low viscosity (water-like). Therefore the viscosity ratio to the polymer melt is normally > 1:106). The Sulzer mixer geometry along with the special Sulzer distribution device has proven its efficiency for these applications in many industrial references. Our engineers are capable of designing the mixer in such a way, that the required shear force in the mixer is big enough to overcome the surface force in order to form the required droplets.

Customer advantages

The unique elongational shear forces created by the Sulzer mixers ensure optimum performance within shortest possible installation length.

For critical applications, or if the known physical properties of the chemicals involved are not available, customer tests for special applications can be made in our in-house laboratory.

Compared to dynamic system, static mixers have no need for maintenance and the energy requirement is a fraction of a dynamic solution. The shear forces required to form the dispersion are not always extremely high, therefore static mixers are a true and cost effective alternative solution.
