Polyethylene Cross-linking (PEX or XLPE)
XLPE, or high-density crosslinked polyethylene, is a kind of polyethylene with a crosslinked structure that is particularly intended for critical applications. XLPE Applications Cross linked polyethylene is made by combining polyethylene under pressure with organic chemicals, which results in the formation of a free radical.
The free radical causes the polymer to crosslink, resulting in a resin that is especially intended for essential applications such as chemical storage pipework systems, hydronic radiant heating and cooling systems, and high voltage electrical cable insulation.
XLPE Characteristics
- Temperature extremes
- Resistance to hydrolysis
- Electrical and insulation characteristics are excellent.
- Abrasive wear resistance is high.
- High extrusion speed on typical lines Potable water certified
- Cost savings
- Mechanically more durable
XLPE cables are by far the most common, and XLPE offers several advantages in a variety of electrical applications to its moisture resistance, stress resistance, and superior protection against heat comes in different to other equivalent power cables. When comparing XLPE with PVC cables, XLPE power cable has:
- Significantly extended service life
- Better heat resistance, XLPE power cable can normally withstand temperatures of up to 260°.
- It has higher tensile strength and impact resistance.
- Better eligibility for existing applications with higher ratings
