Enclosure Shielding - Conductive Elastomer

Waveseal Conductive Elastomers are designed for applications which require both EMI shielding and environmental sealing. The compound formulations are developed by combining elastomeric polymers with highly conductive fillers, providing excellent EMI shielding and sealing across a wide temperature range. All formulations are compounded to be compatible with common fluids and to resist compression set resulting in years of continuous service. Waveseal Conductive Elastomers are available in standard and custom configurations including Extruded Profiles, Sheet Stock, Custom Molded, and Die-Cut gaskets.
