Electrically conductive tapes and processes

An essentially flat, electrically conductive tape oriented in at least a longitudinal direction and having an essentially rectangular cross-section and a thickness of about 30 to about 180 microns and comprising at least one conductive layer and at least one substantially nonconductive layer adhered in a laminar configuration at an interface therebetween with at least one such conductive layer providing an external surface of the tape, wherein

• the conductive layer or layers makes up about 30 to about 60 percent of the thickness of the tape and comprises at least one thermoplastic resin and has dispersed therein an amount of electrically conductive particles ranging from about 25 to about 35 weight percent of each such layer and
• the substantially nonconductive layer or layers comprises at least one thermoplastic resin and is at least substantially free of electrically conductive particles and
• the electrically conductive tape has electrical resistivity up to about 1.times.10.sup.8 ohms, tenacity in the longitudinal direction of at least 2.0 cN/dtex and elongation of 15 to about 25%.
