Abstract
A polyarylether composition (C) comprising: at least one poly (aryl ether ketone) polymer (“PAEK polymer”), at least one poly (biphenyl ether sulfone) polymer (“PPSU polymer”) and/or polyethersulfone (“PES polymer”), at least one electrically conductive fibrous carbon-based filler (“component B1”), and at least one electrically conductive particulate carbon-based filler (“component B2”). An article, particularly for electrostatic dissipative applications, such as a substrate carrier, comprising the polyarylether composition (C). The polymer composition is suitable for electrostatic discharge application.
