Full Name
Polyethylene (PE)

Polyethylene is a thermoplastic polymer with variable crystalline structure and an extremely large range of applications depending on the particular type. It is the most widely produced plastic in the world and is most commonly used in packaging.

Polyethylene is commonly categorized into one of several major compounds of which the most common include LDPE, LLDPE, HDPE, and Ultrahigh Molecular Weight Polypropylene.

PE in Telecommunications

PE is frequently chosen as the material for this outer jacket due to its excellent physical and electrical properties. One of the key attributes of PE is its high resistance to moisture and chemicals. This makes it an ideal choice for applications where the cable might be exposed to humidity, rain, or potentially corrosive substances.

PE offers superior durability as it is physically tough and resistant to abrasion, which is essential for protecting the cable during installation and throughout its service life. This durability means that coaxial cables with PE jackets can withstand rough handling and harsh environments while maintaining their integrity and performance.

For applications where the cable may be directly exposed to outdoor environments, special consideration must be given to the cable jacket's resistance to ultraviolet (UV) radiation. Standard PE is not inherently UV-stable and can degrade over time with exposure to sunlight. However, PE can be made UV-stable through the addition of specific UV stabilisers during the manufacturing process. These additives absorb or reflect the UV radiation, thereby preventing it from breaking down the polymer chains in the PE material.

UV-stabilised PE jackets are thus better suited for outdoor applications, as they can withstand prolonged sunlight exposure without significant degradation in their mechanical or electrical properties. This feature extends the lifespan of the cable and ensures the consistent transmission of signals, making UV-stabilised PE an excellent choice for outdoor telecommunications infrastructure.
