EcoGentle^®

Extrusion the gentle way

Innovative EcoGentle^® plasticising technology, in combination with EREMA's proven Counter Current^® technology, ensures perfect interaction between the intake section and the extruder screw. Temperature and energy requirements are greatly reduced, while at the same time improving melting and mixing performance in the plasticising unit.

Ingenious process technology.

Rheologically optimised. The core elements of EcoGentle^® technology are the adjustment of compression ratios for better solids handling behaviour, the targeted utilisation of shear flows in combination with expansion flows, and a number of other process and rheological optimisations. The perfectly-matched interaction between the shear and elongation flows increases both the melting performance and the dispersive and distributive mixing capacity in the plasticising unit.

Wider process window, more stable operation.

The result is particularly gentle plasticising combined with high melt homogeneity and a wide process window for more stable operation. Variations in parameters such as the bulk density of the input material, its viscosity, and temperature can be compensated as part of the stable process.

EcoGentle^® stands for a particularly gentle method of plasticising at lower temperature that saves energy. The much lower melt temperature has a positive effect on the quality of the melt and the quality of the final recycled pellets.
