Foam extrusion systemsKraussMaffei Berstorff has been designing and building extrusion systems with state-of-the-art technology for many decades – from individual foam extruders up to complete extrusion lines for physical foaming processes.
Schaumex and Schaumtandex extrusion lines are ideal for
- processing PS, PE, PP, PET and other polymers without changing the screw or barrel configurations,
- using eco-friendly blowing agents (CO2 and hydrocarbons),
- recycling start-up scrap, edge trims, web scrap, etc. easily and effectively.
