PROCESS TYPES

Mixing Processes in the Plastics Sector

Each process type requires different mixing parameters, impeller geometry and material selection.

Polymerization

Controlled mixing in bulk, solution, suspension and emulsion polymerization. Impeller design adaptive to viscosity increase.

Polycondensation

Mixing under high viscosity and vacuum for PET, PA and PC production. Surface renewal and volatile removal.

Compounding

Homogeneous dispersion of fillers, colorants and additives within the polymer matrix.

Chemical Recycling

Waste plastic recovery in pyrolysis, solvolysis and depolymerization reactors.

Epoxy & Resin

Two-component thermoset resin mixing. Pot life management and homogeneous hardener distribution.

Emulsion Polymerization

Particle size control in latex and acrylic dispersion production. Mixing that prevents coagulation.

WHY MECHANIMIX

Why Mechanimix for the Plastics Industry?

Mixing errors in polymer reactors lead to gel formation, hotspots and inconsistent molecular weight distribution. Mechanimix provides optimum mixing in the same reactor across both low and high viscosity regimes with dual impeller systems. Using CFD simulation, we detect dead zones in advance and maximize reactor efficiency.

FAQ

Frequently Asked Questions

Which mixer type is used in polymerization reactors?+
In suspension polymerization, the HWM wide-blade impeller ensures homogeneous particle distribution. In emulsion polymerization, the higher-shear HM impeller is preferred. The HP Series pressurized reactor mixers operate at up to 150 bar.
What type of impeller is used for high-viscosity polymer mixing?+
For viscosities above 10,000 cP, the HVM high-viscosity impeller is used. Its narrow blade geometry provides effective shearing near the vessel wall. Scraper blades increase jacket heat transfer.
How is temperature controlled in polymer reactors?+
Polymerization is an exothermic reaction; the RC-M series double-jacketed reactors remove reaction heat in a controlled manner. A jacket plus coil combination can achieve ±1°C accuracy even in large-scale reactors.
Why is vacuum drying preferred for polymers?+
Residual moisture and solvents in polymer granules degrade product quality. The VD-M vacuum dryer enables efficient drying at low temperatures, preventing thermal degradation. A spiral agitator guarantees homogeneous moisture removal.
How is the mixer selected for PVC and PE production?+
In PVC suspension polymerization, the HWM-B wide-blade impeller provides homogeneous suspension at low shear. For PE production, due to high pressure and temperature conditions, the HP Series mixer with Hastelloy or Titanium material options is evaluated.
