The 3M™ Embossed Copper Foil Tape 1245 is an acrylic adhesive EMI shielding tape. This flame retardant tape is designed for applications that require outstanding electrical conductivity. It comes on a removable liner for easy die cutting and handling. The tape is rated for 600V dry applications.The 3M Embossed Copper Foil Tape has embossed, deadsoft, copper foil backing with a pressure sensitive, acrylic adhesive that ensures firm adherence. The conductivity of the adhesive used in the tape offers good shielding effectiveness and stable contact resistance. The copper foil backing of the tape offers excellent resistance against oxidation and discoloration. Contact between the backing and the application substrate is established when the embossed backing edges cut through the adhesive layer. UL Listed and RoHS 2011/65/EU Compliant.
