General description

Indium tin oxide coated polyethylene terephthalate (PET) film is optically transparent and electrically conductive.The ITO coating is protected by a thin, transparent film, that can be easily peeled off.


1, 5 ea in rigid mailer


A radius of curvature of up to 75 mm will not damage the ITO coating. Carbon nanomaterial coated ITO –PET offer a new class of transparent organic light emitting diodes. ITO-PET was used as a magnetic target for MALDI.

Features and Benefits

The polyester film products comprise sputtered ITO, and exhibit transmittance and resistance characteristics similar to those of the glass substrates.

Physical properties

Thickness of ITO coating is 720 Å


5 ea = 5 x 1ft x 1ft

What is the Department of Transportation shipping information for this product?
Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product.
Why isn'tthe Indium tin oxide (ITO) coated PET showing resistance?
The Indium tin oxide (ITO) coated PETis protected by a thin, transparent film that can be easily peeled off. This film will not show resistance, so it needs to be removed prior to testing the electrical properties.
How do I determine which side of this product has the Indium Tin Oxide (ITO) coating?
The ITO side of the PET sheet has a blue protective film on it to prevent the ITO from scratching.Once this film is removed,you can also determine the coated side bytestingfor ITO resistanceusing either a Multimeter or a Four Point Probe.
