XLPE Peroxide cross-linked Compounds:

Polyethylenes (PE) have outstandingly good insulation properties. A temporary temperature rise, e.g. due to peak loading, can however cause a complete breakdown of PE cable insulation. The relatively low softening or melting point leads to thermo-mechanical failure or even dripping of the Insulation. Cross-linked polyethylene (PEX) is more thermosetting than thermoplastic. It can therefore be used at significantly higher operating temperatures, is mechanically stronger, more resistant to organic liquids, and often enables thinner wall thicknesses. Various cross-linking methods are used.
The basic formula of peroxide cross-linked XLPE includes PE and peroxide. The peroxide liquid can be injected to co-kneader from hollow pins, which provides a free adaptation in barrel position and high outstanding mixing effect due to peroxide injected to polymer directly.
The co-kneader has mild shearing to the whole process, and an easy switch-over is realized.
