Flex-Shield Conductive Film

Flex-Shield is a vacuum deposited multi-layer coating on flexible clear polyester film. It is available on 125 and 175 micron thick polyester and in two levels of conductivity, Flex-Shield 10 with a sheet resistivity of less than 12 ohms/sq.( typically 10 ohms/sq.) and Flex-Shield 20 which is less than 25 ohms /sq. (typically 20 ohms/sq.)

The coatings are optically neutral and have high visible light transmittance. Flex-Shield 10 has visible light transmittance of > 74% and Flex-Shield 20 > 80%.

Flex-Shield is stable in humid environments, showing a resistivity change of only 1% when exposed to 24h 95% RH at 49 deg C, and good thermal stability to 80 deg C , resistance change of 2% after 72 hours at 80 deg C.

The minimum bend radius of the product is 3mm but somewhat higher if the conductive coating is on the outside of the bend.

Flex-Shield is available in sheet form, as die cut shapes or as rolls up to 1.2 m wide and 1000m long. Flex-Shield can also be supplied with the additional options of a peelable protective film on both faces and an optically clear pressure sensitive adhesive on the non-conductive face.

Although Flex-Shield has been developed for the EMC Shielding market other applications include:- Touch Panels, Membrane Switches and Transparent Heating Elements.
