Polymer Production and Chemical Polymer Recycling

It is the production of polymers where the right mixing solution decides about the final product quality. On the other hand, plastics recycling is of rising importance due to environmental reasons. Chemical recovering processes also involve mixing in various process steps.

Mixing Solutions for Plastics Manufacturing & Recycling

In the plastics manufacturing the number of different products and processes is manifold. Polymerization or polycondensation processes follow different mechanisms. They might run batchwise or continuously. For this vast range of applications EKATO can help to find out the mixing requirements in order to find an optimum mixing solution.A fundamental challenge associated with the manufacture of polymers and plastics is the removal of the heat of reaction. At the start of polymerization, heat removal is simple because the initially formed oligomers have a low viscosity owing to their small degree of polymerization. As the reaction proceeds, the viscosity of the polymers may dramatically increase over time. Barriers to heat and material transport develop. Control of these by mixing is crucial in order to obtain particular polymer grades.

Advanced plastics recycling, also called chemical recycling, refers to several different technologies that convert used plastics into their original building blocks, specialty polymers, feedstocks for new plastics, fuels, waxes, and other valuable products.

EKATO’s Technology Center provides the maximum flexibility to develop and optimize agitation systems applied in polymer recycling. We welcome you to check the potential of new impeller types, components and reactor systems thus guaranteeing tested quality levels. Along with developing solutions, EKATO’s main focus is on analysing the impact of operating modes, raw materials and energy savings and comparing different machine and process concepts. The use of modern simulation methods complements the trials and helps to find the best settings in a cost-effective way.

For this wide range of applications, EKATO helps to determine the specific mixing tasks in order to find an optimal process solution

What does “Number of sealing faces” mean?

Single-acting mechanical seals
These seals have one sealing surface and only seal in one direction. They are generally simpler in design and are commonly used in applications where pressure is applied from only one side.

Double-acting mechanical seals
These seals have two sealing surfaces and can seal in both directions. They are ideal for applications where pressure may come from both sides or where a higher sealing performance is required.

Triple-acting mechanical seals
These are less common and used in specialized applications that require a more complex sealing setup. They offer additional sealing surfaces or mechanisms to ensure reliable sealing even in highly demanding environments.
