ECG7073H 3M

Technical Data December 2013 3M Electrically Conductive Cushion Gasket Tape ECG7033H ECG7053H ECG7073H Product Description 3M Electrically Conductive Cushion Gasket Tapes ECG7033H, ECG7053H, and ECG7073H are electrically conductive compressible gasket tapes in a single coated tape format with good electrical conductivity and excellent cushion/ recovery properties. The 3M ECG7000H Series tapes offer excellent gap filling performance while maintaining good electrical grounding potential. These products offer conductivity through the thickness (Z-axis) & in the plane of the adhesive (X-Y planes) and are ideal for EMI/EMC gasket tape applications between common substrates, such as metal surfaces (including metal plated substrates). These products consist of a soft & conductive polymeric foam gasket and thin electrically conductive adhesive tape laminated on mesh fabric side (liner side) of the cushion gasket. The conductive adhesive is a high performance 3M Electrically Conductive Adhesive Transfer Tapes (ECATT). The 3M ECG7000H Series tapes are useful for EMI/ RFI shielding & grounding in electronics and electrical devices. The 3M ECG7000H Series tapes may be applied in strips or die cut to specific shapes and sizes. Compared to screws or other mechanical connectors and grounding means, the 3M ECG7000H Series tapes can provide for reduced assembly time and a solid bond line with no bond line gaps which might result in EMI emissions. 3M ECG7000H Series tapes are supplied in a 3M logo printed paper liner configuration for easy handling and convenient die-cutting properties. 3M ECG7000H Series tapes are available in standard size and custom sizes (widths and lengths).
