Informazioni di Base.
Descrizione del Prodotto
Aste di politetrafluoroetilene
Asta in PTFE: Diametro esterno: 6-800 mm, lunghezza: 100 mm
Il PTFE ha il punto di fusione più alto ed è in grado di continuare a funzionare a -180-260 C. il PTFE è una resina che può essere processata allo stato fuso in grado di continuare a funzionare a 204 C. i prodotti PTFE come le guarnizioni in teflon sono utilizzati come guarnizioni e materiali di imballaggio in apparecchiature di lavorazione chimica; come isolamento elettrico per la massima affidabilità; e nei cuscinetti, guarnizioni, fasce elastiche e altre applicazioni meccaniche, in particolare quelle richiedono caratteristiche antiaderenti. Il PTFE ha eccellenti proprietà di isolamento termico ed elettrico. Ha un basso coefficiente di attrito.
