The twin-screw corotating extruder is greatly used for processing those raw materials particularly sensitive to thermal and mechanical stress, for example in cable production.

In this area, ICMA has developed a very skilled technology for the production of some types of compounds, such as Cross-Linked compounds silane/peroxide-based or peroxide base for low-medium voltage (XLPE), Flame-Retardant compounds (FR), and “Halogen-Free” compounds (HFRR). In these applications, the mixing quality – further to the high dispersion degree – and temperature control are key for good processing.
