Flexshield 15 – Conductive EMC Polyester Film
Flexshield 15 is a highly conductive coated optically clear polyester film. The combination of high visible light transmission,
near neutral colour and low electrical resistance make an ideal EMC, EMI or RFI shield for electronic displays, touch screen
and membrane switch panels requiring moderate shielding effectiveness and high quality optical properties. The thin film is ideal
for easy integration into optical stacks and displays.
Flexshield 15 is a 175micron polyester film with a vacuum deposited conductive coating on one surface. This coating is durable and is not liable to cosmetic damage such as oxidisation from moisture or finger prints like a silver based coating.
Parts can be supplied fitted with a PSA gasket on the non-conductive side for ease of assembly or to provide spacing to prevent the optical distortions (Newton Rings).
Direct contact can be made to the conductive surface by a suitable conductive fabric over foam gasket, silver loaded silicone gasket or by using a conductive adhesive tape such as copper, aluminium or tinned copper. Do not use busbar paints or gaskets containing metal wires
