Featuring outstanding heat stability*, tensile strength (220 MPa TD/MD) and elongation percentages (TD 110%; MD 130%), PEN (polyethylene naphthalate) film is highly transparent (haze 2%; total light transmittance 87%), smooth-surfaced and offers good resistance to chemicals including:
- Greases and Oils
- Halogenated Hydrocarbons
- Aromatic hydrocarbons
Resistance to diluted acids is also good, while resistance to concentrated acids is good to poor.
A semi crystalline substance, PEN film also has low moisture permeability. These properties makes PEN film the perfect material for use in optoelectronic, optical and electronic applications. Good optical transparency also means PEN film has the capacity to be useful as a superstrate/substrate within solar cells’ heterostructure.
*Thermal shrinkage data:
150 deg C×30 mins.: TD – 0.0% and MD – 0.1%
200 deg C×10 mins.: TD/MD 0.3%
ITO Coated PEN Film
For optoelectronic and electronic applications, PEN film is typically required to be rendered electro-conductive, which can be achieved by coating the film with indium tin oxide via sputter application. ITO coated PEN film offers all the electro-conductive, optical and mechanical properties necessary to make it the perfect solution to the requirements of many industries.
