Expanded graphite sheets-4

La grafite espansa rappresenta oggi la piu avanzata soluzione dei materiali per guarnizioni. La purezza della grafite utilizzata (98%) ed i procedimenti di lavorazione mediante compressione, senza l'utilizzo di materiali di riempimento o legatura, garantiscono l'alto grado di qualita del prodotto finito. La particolare fragilita della grafite durante le fasi di manipolazione ha portato alla realizzazione di fogli con inserto metallico interno in acciaio inox sia liscio che a grattugia. Dati generali di fornitura: Formato dei fogli: • Standard 1000 x 1000 mm • A richiesta 1500 x 1500 mm Spessori...
