Meeting the latest challenges in grounding and EMI shielding.

For decades, 3M has been a trusted resource for EMI shielding, electrical grounding, and protection from electrostatic discharge. This expertise across multiple industries has been instrumental in developing today’s EMI/EMC solutions for automotive display systems – especially display printed circuit boards and flexible printed circuit boards (PCBs).

EMI grounding and shielding tapes, together with our EMI absorption materials, combine our longstanding expertise in adhesives and functional fillers. These materials are developed on decades of experience blocking and absorbing EMI across a broad range of frequencies, and optimising electrical signal-to-noise ratios (SNR). Ideal for applications including ITO touch sensors, our industry-standard tapes feature metal foil or metallized fabric construction and electrically conductive adhesives that direct noise away from critical components, deliver low and stable contact resistance and maintain consistent performance even in tough environments. Our EMI absorbers employ magnetic flake filled polymer resins to absorb noise around critical components.

All of our EMI management materials are manufactured for efficient conversion, handling and application. They are available in a variety of thicknesses and configurations to meet your attenuation requirements. Pressure-sensitive acrylic-based adhesives eliminate cure times and the added cleanup associated with liquid adhesives. Release liners can be removed with or without automated equipment. All materials are easily die-cut.

A selection of metal foil or metallized polyester fabric backed conductive tapes allows you to meet specific application requirements: stable conductivity, small grounding areas, high shielding performance, conformability to irregular surfaces, handling, reworkability and more. Most of our EMI shielding and grounding tapes are halogen-free. These tapes feature conductive acrylic-based pressure-sensitive adhesives. Transparent PET liners are available for efficient conversion and processing.

Our EMI absorbers are particularly well-suited for helping prevent EMI from internal sources around digital display devices. Acrylic pressure sensitive adhesive is applied to a high magnetic-permeability composite made from polymeric resin and magnetic metal flake filler. The material is available in sheet form and can be easily die cut into complex shapes.
