Abstract
Inventia se refera la un procedeu de regenerare a polietilenei de înalta densitate prin supunerea maruntirii, spalarii si uscarii polietilenei de înalta densitate provenita din obiecte scoase din uz, se amesteca aceasta cu un concentrat granulat în proportie de 20-50% fata de polietilena uzata de modificator de regenerare ales dintre polimer etilena-propilena cu vîscozitate Mooney peste 50, bloc copolimeri de tipul, stiren-butadiena-stiren sau amestecuri ale acestora, amestecul obtinut se omogenizeaza în masini de extrudere prevazute cu filtre de îndepartare a impuritatilor din topitura si cap de granulare de tip cunoscut.
