Abstract (en)

[origin: EP0386975A2] Melt-spun filaments are provided of a polymer capable of retaining its strength at a temperature of 170 DEG C. The filaments contain 5 to 25% by volume of an electrically conductive filler such as carbon. They can be used to form a filter for hot gases, for example as a fabric formed from a mixture of such filaments and filaments from such a polymer which do not contain conductive filler.
