PLASTINUM Extrusion Foaming with CO₂

Maximising the benefits of carbon dioxide for extrusion foaming

Our PLASTINUM® Extrusion Foaming portfolio was designed specifically to meet the challenges of precisely metering liquid carbon dioxide (LIC) into the extruder. A constant mass flow of carbon dioxide is crucial for uniform, predictable foaming results. Based on our long-standing knowledge and experience in this field, we offer a one-stop solution extending from an LIC bulk tank to a DSD high-pressure metering unit. For customers who already have a metering pump in place, we offer a state-of-the-art supply system for bubble-free liquid CO2 at a defined pressure.

End-to-end offering

Our PLASTINUM Extrusion Foaming solution comprises a customised LIC storage and supply system, a pressure boosting unit and a high-pressure flow metering system. At the first stage, our PRESUS® C pump system increases the LIC pressure and delivers LIC in a bubble-free state. In the second stage, our proven DSD 400 or DSD 500 high-pressure metering unit supplies a stable mass flow of LIC into the extruder, irrespective of pressure fluctuations in the extruder.
