The thermal scanning procedure, including melt and crystallization, follows below: (1) melt behavior, staying 5 min at -50 C then heating (10 C/min) to 350 C; (2) crystallization behavior, ETFE. 00 - 40. 5–2. The table below lists average deflection temperatures at 0. With an ETFE roof or façade system, there are three ways in which smoke ventilation can be ensured. Some ETFE insulations fail flammability in a 30% oxygen environment. ETFE resin now becomes easier to use with better performance. 92% after 1. Compared to glass, ETFE film is 1% the weight, transmits more light and costs 24% to 70% less to install. ETFE : 10126: 32 - 4/0: 600: 150°C: 0. Nylon 11 is seen to have increased dimensional stability in the presence of moisture due to its low concentration of amides.
