Extrusion and compounding
Development of plastic-material formulations based on:
Depending on the final amount of plastic material and in keeping with the nature of the components of the formulation, we work on two kinds of processes:
The chemical modification of polymers such as PP, PE or PLA is carried out during the extrusion process by treating them with peroxides or by grafting molecules of different chemical nature (DEM, MAH, silanes, etc.) in order to:
Finished or semifinished products based on flat profiles – films or sheets – applied to packaging, packages, decorative films or sandwich-type structures.
New colours and surface finishes can be obtained with a single screw extruder with coupled calenders working at temperatures up to 450 degrees.
