Silver Conductive Film
Silver Conductive Film is an electrically conductive, silver alloy coated, optically clear, low resistance polyester EMI/RFI shielding film. The combination of high visible light transmission, near-neutral color, and low resistance creates the ideal EMI/RFI protection window for electronic displays, touch screens, and membrane switch panels that require moderate shielding effectiveness and high-quality optical performance. It is optimal for use as EMI/RFI shielding for Industrial, Defense, and Medical displays, touch screens, solar photovoltaic material and conductive transparent electrodes.
