Crosslinked Polyethylene - XLPE

Polymer Type

Thermoplastic

Advantages

Higher modulus and strength at elevated temperatures.  Reduced creep compared to HDPE.  Reduced sensitivity to stress cracking.

Disadvantages

Irradiation cross-linking requires expensive plant.  Peroxide cross-linking can affect electrical properties.
