KraussMaffei launches the new ZE Petrochemical (ZE-PC) series for industrial raw polymer production. This powerful co-rotating twin-screw extruders were developed specifically for the requirements of the petrochemical industry and mark the company's entry into this highly dynamic market segment.

Visitors at K 2025 will have the opportunity to learn more about the new ZE-PC series from live presentations, animations, and personal discussions with experts from sales and process engineering.

KraussMaffei’s new ZE Petrochemical (ZE-PC) series.

Flexible, process-optimized, and energy-efficient operation

The new generation is based on KraussMaffei Extrusion's proven BluePower technology and impresses with outstanding energy efficiency, high processing capacity, and optimized product quality.

With screw diameters ranging from 260 to 330 mm, and potentially up to 400 mm, the new ZE-PC offers a highly scalable solution for large-volume polymer processes.

The new ZE-PC extruder also impresses with an exceptionally high Da/Di ratio of 1.65 and a high torque density of up to 16 Nm/cm³. A variable-speed drive also enables flexible and process-optimized operation.

The low screw speeds significantly reduce the risk of thermal degradation of the material. At the same time, the reduced melt temperatures enable higher throughput and a wider process window with lower energy input. In addition, the larger diameter ratio ensures significantly more effective degassing.

Wide range of applications in polymer production

The ZE-PC series was designed for demanding applications in raw polymer production, especially for degassing processes in the melt-to-pellet sector, but also for powder-to-pellet applications with optional degassing. 

In addition, the series is suitable for large-scale industrial chemical or solvent-based recycling processes. Three ZE-PC 330 machines for a leading petrochemical group in China are already being delivered.
