New Modifications of Chemically Crosslinked Polyolefin Based Pipes [PEX]

Continuous high-temperature peroxide crosslinking of polyethylene is now a well-established technology in production lines of cable and wire insulation. A single-stage, highpressure technology where the pipe forming operation and crosslinking reaction take place in the same machine was developed by Thomas Engel & Co. New versions of crosslinked polyethylene pipes including W protected, selfextinguishing, antistatic and electrically conductive have been developed. All these crosslinked pipes emerge continuously from the die and no further operations, besides final calibration and cooling, are required.
