Abstract: A process for for making a cross-linked polyethylene article includes: (A) feeding a blend comprising a cross-linkable silane-group containing polyethylene copolymer and at least one additive to an extruder, (B) feeding a liquid comprising a silanol condensation catalyst to said extruder to form a mixture with said blend, (C) extruding said mixture to form an article and (D) cross-linking said article. The article may be a pipe or cable.

Abstract: The present invention relates to a process for making a cross-linked polyethylene article and to the use of such a process in the production of pipes or cables. The process comprises: (A) feeding a blend comprising a cross-linkable silane-group containing polyethilene copolymer and at least one additive to an extruder, (B) feeding a liquid comprising a silanol condensation catalyst to said extruder to form a mixture with said blend, (C) extruding said mixture to form an article and (D) cross-linking said article.

Abstract: The application relates to a process for preparing a crosslinked cable, including:—applying one or more layers including a polymer composition on a conductor, wherein at least one layer includes one or more free radical generating agents,—crosslinking by radical reaction said at least one layer comprising said free radical generating agent(s),—cooling the obtained crosslinked cable in pressurized conditions.

Abstract: An optical fibre submarine repeater cable with combined insulation/jacket is disclosed as well as a composition therefore. The optical fibre submarine repeater cable with combined insulation/jacket is characterised in that the combined insulation/jacket comprises a multimodal polyolefin with a density of 0.910-0.960 g/cm3 and an MFR2 of 0.2-6.0 g/10 min, and that the combined insulation/jacket is free from particles with a dimension larger than 0.5 mm in a 1 kg sample of material. Preferably the multimodal polyolefin is selected from ethylene and propylene (co)polymers and is bimodal.
