Silicone Crosslinked Polyethylene (PEX) is a polyethylene material modified by silane crosslinking technology, featuring a three-dimensional network crosslinked structure. Its main chain forms Si-O-Si bonds through hydrolysis condensation. Compared with the traditional C-C bond cross-linked structure, it has better heat resistance and mechanical properties.
Availability:
Quantity:

Compared with uncrosslinked polyethylene, cross-linked polyethylene has:

Longer service life at higher temperatures

Better aging resistance

Better creep resistance

Better chemical resistance

Better impact resistance

Better wear resistance

Better resistance to crack rapid diffusion

Excellent resistance to slow crack growth

Better resistance to environmental stress cracking


Advantadge:

1. It has excellent heat resistance and can maintain stable performance within a wide temperature range of -70 ℃ to 110℃, meeting the requirements for the transportation of cold and hot fluids.

2. It has good flexibility and strong impact resistance, is not prone to brittleness in low-temperature environments, can be bent and shaped during installation, and can adapt to complex laying scenarios.

3. It has high chemical stability, strong resistance to various acids, alkalis, organic solvents and impurities in water, and is not prone to corrosion or scaling, thus extending its service life.

4. It has a moderate thermal conductivity and certain heat preservation performance. In hot water delivery or floor heating systems, it can not only effectively transfer heat but also reduce energy loss.


Application:

1. Petrochemical industry: Used in fluid conveying pipelines.

2. Construction: As piping for household water heater systems.

3. Heating system: Provides corrosion resistance and heat resistance.

4. Power system: Cross-linked polyethylene cable material is used as the covering material for wires and cables, featuring wear resistance and high insulation resistance.

5.Kitchen and bathroom industry: used for kitchen pull-out pipes, shower pipes.
