The present invention relates to a crosslinkable high pressure polyethylene composition containing ethylene silane copolymer resin having a content of silane of about 0.1 to 10 weight % and at least one silanol condensation catalyst. The invention further relates to a process for the preparation thereof, to a pipe made of said composition and to the use of the composition as an insulation for a cable.

Crosslinkable high pressure polyethylene composition, a process for the preparation thereof, a pipe and a cable prepared thereof

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 MFR2 measured under a load of 2.16 kg and at a temperature of 190&#xb0; C. of component (A) to the MFR2 measured under a load of 2.16 kg and at a temperature of 190&#xb0; 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 MFR2 measured under a load of 2.16 kg and at a temperature of 190&#xb0; C. of component (A) to the MFR2 measured under a load of 2.16 kg and at a temperature of 190&#xb0; C. of the composition is higher than 3.5, the cable or wire further comprising at least one further layer.

Power or communications cable with flame retardant polymer layer

A low voltage power cable having an insulation layer with a density below 1100 kg/m, which has a polyolefin having 0.002-4% mol of a compound that has polar groups and further having a compound that has hydrolysable silane groups and includes 0.0001-3% weight of a silanol condensation catalyst and a process of manufacturing such a cable.
