Preparation of foils or plates from thermoplastic with electrical conductive coating, comprises: coating one-side of a carrier foil from a thermoplastic with a varnish composition; extruding a melting rank of the thermoplastic on an extrusion equipment by a broad slot extruding nozzle for plates or foils with roller grazing; bringing the coated side of the carrier foil, where a composite of the coated carrier foil that is developed with melting rank; removing the carrier foil from the composite; and cooling the plastic sheet at room temperature. Preparation of foils or plates from thermoplastic with electrical conductive coating, comprises: coating one-side of a carrier foil from a thermoplastic with a varnish composition containing silicon-oxide particles and inorganic semiconductor particles in a solvent or its mixture, and optionally an auxiliary leveling agent, blades, tides, dipping or continuous coating and following drying; extruding a melting rank of the thermoplastic, a lower softening temperature, thermoplastic of the carrier foil, on an extrusion equipment by a broad slot extruding nozzle for plates or foils with roller grazing; bringing the coated side of the carrier foil with the malting rank of the extruded thermoplastic in the roller grazing and a roller temperature of more than 5[deg]C under the slumping temperature of the extruded thermoplastic, where a composite of the coated carrier foil that is developed with melting rank; removing the carrier foil from the composite; and cooling the plastic sheet at room temperature. An independent claim is included for extruded foil or plate, which is obtained by using the above procedure, comprising thermoplastic has electrically conductive coating with a surface resistance of smaller 1010> omega , where the surface resistance increases after a scrubbing load according to DIN 53778 of 5 cycles, by not more than one decimal power. |
