Polyimide electric film

1. Introduction polyimide film electric film (referred to as a heater), is a polyimide film as an outer insulator; ﹑ metal foil for the inner conductive wire heating element, heat from high temperature and pressure. Polyimide film having excellent electric insulation strength; excellent dielectric strength; excellent thermal conduction efficiency; excellent resistance stability. This makes it possible to be widely applied in the field of heating and access to a relatively high temperature control accuracy. Polyimide electric film has been successfully used in satellite Fengyun series, the Long March series of carrier rockets, Dongfeng ﹑ red series of missiles, as well as aircraft, ships, tanks, artillery gyroscope, accelerometer, fire control radar, such as temperature and heating systems. Applied in civilian areas in warm fabric tester, thermal conductivity detector, bath, development and production of automotive air-conditioning governor resistors, automotive rearview mirror defrosting sheet, refrigerators thermal compensation heater, bathroom mirror heater. 2, Technical Specifications a dielectric strength UDC 500V ≥ 200MΩ b dielectric strength UAC ≥ 2000 V c Long-term use temperature ≤ 232 ℃ d heat flux without heat sink without temperature ≤ 1.1W / cm2 heat sink temperature control ≤ 6.5W / cm2 e thickness ≤ 0.20 mm f weight ≤ 278 g / m2 3, heater design guidelines provide a maximum dimensions of parts graphics; b provide electrical heater related parameters such as power, voltage. Or resistance, current, and error; c heater is provided outside the lead qualifying position, direction and length. 4, the manufacturer can provide information about the bonding guide vulcanization curing type ﹑ ﹑ ﹑ hot-melt pressure-sensitive adhesives and other types of use, and bonding process consulting services.
