EXTRACTION OF REGENERATED POLYPROPILEN
Polypropilene that is extracted in the process of battery separation is additionally washed and dried, and then transported into special silos.
Material that is crushed down to about 1 cm in size is taken into further process through the process of extrusion. Here, polypropilen is dissolved, degasified, filtered and cut up to obtain a suitable quality of the extruded regenerated material. Dyestuff is added to obtain the requested colour.
Regenerated polypropilene in black or grey colour is the end product then and it is used for injection moulding of numerous polypropilene products.
