Teonex® PEN Film - Polyethylene-naphthalate Film----[[LIREN ELECTRICAL INSULATION MATERIALS]]

PEN Film has many superior properties such as strength, heat resistance, anti-hydrolysis, dimensional stability, low oligomer extraction, etc.

PEN Film is used in a wide range of electrical and electronics applications including flat-panel displays, touch panels and dry photo resist, information-related applications, high density data storage tapes, IC card, FPC, and automotive applications. It is also used in electronic components such as capacitors, electric insulation, battery and for optical purposes.
