The ITO Coated PEN sheet (Indium Tin Oxide coated Polyethylene Naphthalate) is a transparent, conductive substrate featuring an Indium Tin Oxide layer applied via magnetron sputtering on one surface, with the other remaining insulated. With its superior light transmittance, this film is highly suitable for advanced applications like dye-sensitized solar cells, as it offers excellent thermal stability and chemical resistance.
As a flexible, ready-to-use material, the ITO Coated PEN film is ideal for fabricating various flexible electronics, including touchscreens and sensors. Variants with low sheet resistance are well-suited for applications demanding high conductivity, such as transparent electrodes in thin-film solar cells, electrochromic devices, and thin-film switches. High resistance versions are commonly employed in touchscreen production for mobile communication devices.
PEN, with a chemical structure similar to polyethylene terephthalate (PET), exceeds PET in terms of physical and mechanical strength, gas barrier efficiency, chemical and UV resistance, heat tolerance, and radiation durability. The significantly higher cost of PEN compared to PET limits its broader adoption despite its superior properties.
Developed for the electronics industry, it offers superior properties to PET film, including a thermal stability 45°C higher than PET and corresponding to F-grade thermal performance. It is used across various applications as it exhibits enhanced mechanical performance and lower gas permeability. The ITO Coated PEN sheet is available in sheet form, with a standard size of A4. We also provide custom dimensions tailored to meet the specific needs of researchers. The recommended thickness for the sheets is 125 microns, while the ITO layer thickness ranges from 150 nm to 180 nm.

ITO Coated PEN sheet is used in many industries because of its unique features, such as high light transmission, strong EMI and RFI shielding, and resistance to heat and impact. It is commonly found in display technologies such as LCDs, optoelectronic devices, transparent heaters, and touch panel electrodes. It can also replace ITO Coated PET in smart films for better performance.
The sheet is great for shielding against electromagnetic and radio-frequency interference, supporting touch panels, providing heated clear display filters, preventing static electricity, and working in solar cells. It is widely used in automotive, aerospace, medical imaging, research, military, and consumer electronics, including smartphones and tablets. Its flexibility and reliability make it ideal for advanced technologies in various fields.
