Environmental Stress Cracking of Thermoplastic Polyimide Insulated Wires / Piccin, R (CERN) ; Rigaud, J S (CERN) ; Santillana, I A (CERN) ; Buchanan, K E (CERN) ; Ternova, D (CERN) ; Mitchell, N (Euratom, St. Paul Lez Durance) ; Liao, M (Euratom, St. Paul Lez Durance) ; Luongo, C (EUROfusion Consortium, Garching)
Polyimide is often the first choice to insulate instrumentation and magnet wires working under demanding environmental and operating conditions since it shows good mechanical properties at low temperatures and high radiation resistance. Nevertheless, we have recently discovered that thermoplastic polyimide (TPI) insulated wires may suffer an accelerated brittle failure from a combination of environmental and mechanical stress, summarized as environmental stress cracking (ESC).
