A self-temperature-limiting electrically conducting composite comprises a dispersion in a polymer, e.g. acrylate, of an electrically conducting aggregate such as graphite and an electrically insulating aggregate such as silica or calcite. It is made by mixing the aggregates together with a monomer and a curing agent and allowing polymerization and curing to take place. It can be encased in a polymer cement block to form a heating device. |
