3M™ Ultra Transparent EMI (UTEMI) Shielding Film products 8880 S3 and 8880 S7 comprise a polyester film with an
electrically conductive thin film specialty coating. This transparent conductive coating allows high transmission in the
visible spectrum and provides EMI shielding in the radio and microwave frequency, a unique combination of properties.
Applications include EMI shielding for display screens, (PDP, LCD and CRT).
