Microcell Foam Extrusion
Significant material and cost savings, lighter products, better CO2 balance, more profit!
In extrusion, material accounts for 80% of the CO2 footprint. Promix addresses this with Microcell Technology, which creates a microcellular foam structure in polymers using eco-friendly atmospheric gases. This reduces product weight and typically saves 20-30% in raw materials without compromising mechanical properties. The technology is suitable for a wide variety of applications and for almost all polymers.
Microcell Foam Extrusion from Promix – Outstanding physical foaming solutions
Physical foaming can significantly reduce material costs in many extrusion applications. Foam extrusion systems from Promix set standards in the production of microcellular foam products with a very homogeneous cell structure and high process consistency.
Unique key components and extensive process knowledge form the basis. The systems operate with the environmentally friendly blowing fluids CO2 and N2 and are very easy to integrate into existing or new extrusion lines. Depending on the application, density reductions of 5% to over 70% can be achieved.
