Mixer for Extrusion

The optimum melt polymer quality for extrusion installations is when at each location inside the polymer melt volume a uniform distribution of colorant, additives and melt temperature is measured. Using the Stamixco SMB Melt Blender with 8 mixing elements assures that the homogeneity of the melt is improved by a factor 5-6 or more.

Operating Principle

Static Mixers for Extrusion applications are often called "Melt Blenders". They are installed directly upstream of the die. They homogenize the polymer melt just before forming the end product in the die. Differences in temperature and concentration of colorants and additives are equalized. By this mixing process, polymer melt viscosity differences are reduced to a minimum and thus the polymer flow behavior is optimized. At the same time, colorant spots and streaks are eliminated. This homogenization is achieved by the continuous division and recombination of the molten polymer when pushed through the geometric structure of the mixing elements.
