Zusammenfassung:The present invention in a first embodiment relates to a conduit or automotive wire consisting of an inner conductor core surrounded by a flame retardant layer made of a polymer composition in a continuous process which composition comprises (A) an olefin homo- and/or copolymer, (B) a silicone-group containing compound, and (C) an inorganic filler, wherein the ratio of the MFR 2 measured under a load of 2.16 kg and at a temperature of 190 °C of component (A) to the MFR 2 measured under a load of 2.16 kg and at a temperature of 190 °C of the composition is higher than 3.5, and the wire has a length of at least 100 m. In a second embodiment, the present invention relates to a power or communications cable or wire comprising a flame retardant layer made of a polymer composition comprising (A) an olefin homo- and/or copolymer, (B) a silicone-group containing compound, and (C) an inorganic filler, wherein the ratio of the MFR 2 measured under a load of 2.16 kg and at a temperature of 190 °C of component (A) to the MFR 2 measured under a load of 2.16 kg and at a temperature of 190 °C of the composition is higher than 3.5, the cable or wire further comprising at least one further layer.
