3M™ XYZ Isotropic Electrically Conductive Adhesive Transfer Tape 9709

3M™ XYZ/Isotropic Electrically Conductive Adhesive Transfer Tape 9709 is a pressure sensitive adhesive transfer tape with Isotropic electrical conductivity. Used for EMI shield attachment and grounding applications.

3M™ XYZ Isotropic Electrically Conductive Adhesive Transfer Tape 9709S

Pressure sensitive adhesive. Best adhesion and good XYZ conductivity. Improved contact resistance to stainless steel.

3M™ XYZ Isotropic Electrically Conductive Adhesive Transfer Tape 9709SL

9709SL is a very low liner release version of the 9709S. Pressure sensitive adhesive. Best adhesion and good XYZ conductivity. Improved contact resistance to stainless steel.

3M™ XYZ-Axis Electrically Conductive Adhesive Transfer Tape 7303, 9703

3M's most cost-effective isotropic electrically conductive pressure sensitive adhesive tape. Conductive fibers extend above adhesive for solid electrical connection. Conformable, non-corrosive adhesive reliably attaches EMI/RFI shields and gaskets.

3M™ XYZ-Axis Electrically Conductive Adhesive Transfer Tape 9713

3M's highest performing isotropic electrically conductive pressure sensitive adhesive tape. Conductive fibers extend above adhesive for solid electrical connection. Conformable, non-corrosive adhesive reliably attaches EMI/RFI shields and gaskets.
