1.Laminex film:EVA-General Laminex   (melting point is at 80°C) 

2.Copper busbar:Copper foil mixed with  iron -Black lines are  created. The copper  foil appropriate for film heating must be  thin with a soft surface in order to avoid scratching the silver busbar. 

3.Silver busbar :Plays a role of making sure  power is supplied to the carbon and copper foil. For safety,  the silver busbar between the  copper fo仆and carbon should  maintain a resistance value of l ess than 1 ohm, because the electric  load is applied in places where electricity flows. 

4.Carbon heating part:Strong against heat, and electrical and thermal conduction is high. 

5.Base film (PET Rilm):Less affected by temperature  and humidity due to excellent heat resistance. Transparent film -high transparency (for display)
