Specifiche materiali
Informazioni tecniche dei materiali
PTH, grazie alla pluriennale esperienza nel processo di estrusione dei vari polimeri, utilizza soltanto materiali innovativi e di alta qualità. Per questa ragione, collabora con i maggiori produttori di materie prime al fine di ottenere mescole di materiali con proprietà costanti. Tutti i materiali utilizzati sono certificati.
