摘要

"Process for the production of a polymeric layer of a tube out of the coast not connected flexu00ecvel, method for the production of a tube out of the coast not connected flexu00ecvel, and.The tube off the coast not connected flexu00ecvel ". The invention relates to a process for the production of a polymeric layer of a tube out of the coast non connected flexible.The process comprises the steps of conforming a polymeric material by extrusion in or on a support unit in a season of extrusion and reticularis said extruded polymeric material.Said polymeric material comprising a polyethylene and a peroxide to provide a crosslinking of the polymeric material.The peroxide has an activation temperature substantially above the temperature of the polymeric material during its extrusion.The crosslinking of the polymeric material extruded is performed exposing the polymeric material to electromagnetic waves, selected from the group consisting of infrared radiation and microwave.The invention also relates to a tube out of the coast non connected flexible, comprising such a polymeric layer.
