Crosslinked polyethylene (PE-Xb) is designed for insulating electrical cables across low, medium, and high voltage applications. Standard polyethylene offers excellent electrical properties but has limited thermal tolerance, with maximum operating temperatures of 70°C. When overheated, this can risk conductor exposure.
Our PE-Xb compound solves this challenge by adding specific agents (peroxides, silanes) to low-density polyethylene, enabling crosslinking that creates a three-dimensional molecular structure. This enhancement dramatically improves thermal stability to 90°C operational and 250°C short-circuit conditions.
