Abstract:
The present invention is related to an electrically conductive, hot-melt adhesive or moulding composition, said composition comprising: a) a binding agent which comprises at least one (co)polymer selected from the group consisting of polyamide, thermoplastic polyamide, copolyamide, polyolefins, poly(meth)acrylates, polystyrene, polyurethanes, polyesters, ethylene copolymers, ethylene vinyl copolymers, styrenic block copolymers, polylactic acid, silicones, epoxies and polyols; and, b) a conductive filler comprising particles (p1) which have a mass median diameter (D50) of ≤100 microns and which are selected from the group consisting of flakes, platelets, leaf-like particles, dendritic particles, rods, tubes, fibres, needles and mixtures thereof, wherein said composition has a melt viscosity of from 2500 to 25000 mPa·s as measured at 210°C and is further characterized in that said particles (p1) constitute from 15 to 70 wt.%, by weight of the composition. Preferably, the binding agent comprises at least one (co)polymer selected from the group consisting of polyamide, thermoplastic polyamide and copolyamide.
