When polymers are made, the quality of the final product directly depends on the mixing quality of the process. On the other hand, recycling plastics is becoming more important for the environment every day. The correct mixing technology must be used in the different steps of the chemical recovery process.

The number of different products and processes in plastic manufacturing is huge. Polymerization or polycondensation processes follow different mechanisms. They can operate in batches or continuously. For this wide range of applications, Mechanimix can help find mixing requirements to find an optimum mixing solution. A fundamental challenge with the production of polymers and plastics is the elimination of heat of reaction. At the beginning of polymerization, heat removal is simple because the initially formed oligomers have a low viscosity due to the small degree of polymerization. As the reaction progresses, the viscosity of the polymers can increase significantly over time. Heat and material transport barriers develop. Control of these by mixing is very important to obtain certain polymer grades.

Advanced plastic recycling, also called chemical recycling, refers to several different technologies that transform used plastics into original building blocks, special polymers, raw materials for new plastics, fuels, waxes and other valuable products.

Mechanimix offers new solutions to improve and optimize polymer recycling mixing systems. We invite you to evaluate the potential of new propeller types, components and reactor systems and thus ensure tested quality levels. In addition to designing solutions, Mechanimix’s primary focus is to analyze the impact of operating modes, raw materials and energy savings and compare various machine and process concepts. The use of modern simulation techniques complements the trials and helps determine optimum parameters in a cost-effective manner.
