The amine-based stabilizer N,N′-di-2-naphthyl-p-phenylenediamine (DNP, an antiaging agent), a gray powder, was purchased from Shanghai Shuangguan Chemical Factory (Shanghai, China). Lower T g (glass transition temperature) occurs at –15°C to –20°C and upper T g is in the 40°C to 50°C range. still maintains a service temperature of 150 °C (302 °F). It exhibits excellent chemical resistance, high-temperature stability (up to 260°C or 500°F), low friction, and good electrical insulation properties. For determining melt point and then selecting suitable extruding temperature, thermal analysis was performed (Fig. 05 Table2presents. ETFE film, is now increasingly being applied to the solar industry, it is very suitable for the surface of the solar cell material. 1967. 8MPa C Lower working temperature C Specific heat J K-1 kg-1 Thermal conductivity W m K-1 Upper working temperature C Polyimide PI 30-60 - 360 -270 1090 0. 385 to 400 °C. area factor, ft2/lb 200 100 50 20 Approx. Due toIrradiation The ETFE specimens were irradiated by 7-rays or electron beam (EB) under oxygen-free atmosphere.
