How long is the service life of electrothermal?film?



The service life of electrothermal?films should be 50 years at maximum.
The service life of electrothermal?film has a certain relationship with the quality itself. Now there are many domestic and Korean electrothermal?film in the market, the general warranty of which is about two years, American electrothermal?film is better. The heating system of electrothermal?film is sealed with special printing ink in the interlayer of macromolecular polyester films which can burn-in under constant high temperature condition. The surface normal working temperature of American electrothermal?film is around 40 degrees which is far below the burn-in temperature, therefore its service life is the same as that of buildings.
