20 - 30% material savings through Physical Foaming with Microcell
Since raw material consumption accounts for the largest share of the CO₂ footprint in extrusion, material efficiency is becoming increasingly important. This is where PROMIX Microcell Technology comes into play: The precise addition of environmentally friendly atmospheric gases creates a fine microcellular foam structure within the polymer. Depending on the application, this can reduce the product weight by 20 or more.
In addition to significant material and cost savings, Microcell Technology provides opportunities for product optimization. Depending on the application, properties such as reduced weight, improved thermal and acoustic insulation, enhanced shock absorption, and attractive visual and tactile effects can be achieved.
The technology is successfully used in the production of films, sheets, foamcore pipes, profiles and cable jackets, and is suitable for nearly all common polymers. A new field of application is the foaming of monofilaments. Together with an industry partner, PROMIX is currently developing foamed monofilaments for artificial grass applications.
Microcell technology, which is available for both new installations and retrofits, has now become widely adopted worldwide. More than 350 industrial Microcell systems are already in successful use, and numerous machine manufacturers integrate the technology into their equipment as standard.
The PROCELL foam and nucleating additives have been expanded to include a new grade for PET foams. This is an endothermic blowing agent that does not release water and is therefore perfectly suited for PET. It enables fine cell structures and, at higher dosages, can also be used as a standalone foam additive.
