摘要： A composition which comprises a matrix polymer and, distributed therein, a particulate conductive filler. At least some of the filler particles are composed of a conductive polymer composition and/or the matrix comprises a sintered polymer. The matrix polymer and the filler particles and the method of distributing the particles are such that the particles maintain their identity in the matrix. For example, the particles are preferably highly cross-linked so that they have a hot modulus of at least 250 psi if the composition is prepared by melt extrusion or another process involving a high degree of shear; or a low-shear process such as sintering can be used. Preferably the matrix polymer is capable of coating the filler particles; for example, the matrix polymer and the filler polymer may be chemically similar. The invention is particularly useful for preparing compositions which have high resistivities, e.g. 1000 ohm.cm or more, and which can be prepared with a high degree of reproduceability. The compositions can exhibit PTC, ZTC or NTC behavior, depending on the nature of the conductive filler, and their resistivity is dependent on the electric field. The composition are particularly useful as resistive materials in sheet heaters and as stress-grading materials for high voltage apparatus.

摘要： A dish antenna for receiving or transmitting signals, e.g. via a satellite, is heated by means of radiant heat from an electrical heater located behind the antenna and spaced apart therefrom. This keeps the antenna free from ice and snow and minimizes distortion. The heater is preferably a self-regulating sheet heater comprising a PTC conductive polymer.

摘要： Improvements to electrical devices comprising conductive polymer compositions are described. The device, preferably a heater, comprises two electrodes, preferably planar electrodes and a conductive polymer composition, which preferably exhibits PTC behavior, and which is preferably sandwiched between the electrodes. At least one of the electrodes comprises a metal with a thin layer of high resistivity material attached thereto, e.g. anodized aluminum, so that the layer separates the electrode and the conductive polymer composition. This raises the room temperature resistance of the device and thus reduces the in-rush current.
