Technical Data February, 2010 3M Electrically Conductive Cushioning Gasket Tape ECG-8035 / ECG-8055 / ECG-8075 Product Description 3M Electrically Conductive Cushioning Gasket Tapes ECG-8035 / ECG-8055 / ECG-8075 are electrically conductive compressible gasket tapes in a double coated tapes format with good electrical conductivity and excellent cushion/ recovery properties. The 3M ECG-8035 / ECG-8055/ ECG-8075 offer excellent gap filling performance while maintaining good electrical grounding potential. These products offer conductivity through the thickness (Z-axis) and 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 and conductive polymeric foam gasket and thin electrically conductive adhesive tapes laminated on both sides of the cushion gasket. The conductive adhesive is a high performance 3M Electrically Conductive Adhesive Transfer Tape (ECATT). The 3M ECG-8035 / ECG-8055/ ECG-8075 Tapes are useful for EMI/ RFI shielding & grounding in electronics and electrical devices. The 3M ECG-8035/ ECG-8055/ ECG-8075 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 ECG-8035 / ECG-8055/ ECG- 8075 products can provide for reduced assembly time and excellent conformability to the space between substrates, excellent bond line gap filling which will allow for enhanced EMI shielding and reduced EMI emissions. The 3M ECG products are EMI and grounding gaskets and provide for excellent grounding and EMI shielding. The 3M ECG products are of an open cell design and thus their environmental gasket performance will be limited and must be tested by an end user to see if it meets their environmental sealing requirements (dust, moisture, water, etc.). The 3M ECG products could be used in conjunction with products that are non-conductive and provide for the Environmental Sealing if desired (ex: 3M VHB Tapes). 3M ECG-8035 / ECG-8055/ ECG-8075 are supplied in a dual sided removable liners configuration for easy handling and die-cutting properties. 3M ECG-8035 / ECG-8055/ ECG-8075 are available in standard size and custom sizes (widths and lengths).
