Why Foaming PE insulation needed in Ethernet network cables

With the development of Ethernet technology, and high data transmission requested, so higher performance and better quality Ethernet network cables are required. Today, China leading Ethernet cables manufacturerZion communication are going to talking about something about Foaming PE insulation in building Ethernet network cables

The objective of foaming

The objective of using foaming PE is to reduce the dielectric constant.

Ways of PE material foaming

There are two ways to realize PE foaming. One is Chemical foaming, the other is Physical foaming(Nitrogen foaming). But for some defects of chemical foaming, this way is gradually abandoned by most of the manufacturers.

What is the physical foaming?

With inert inactive gas into the insulating dielectric layer uniform fine porous structure, among each other pores exist independently, similar to a sealed package. The advantage is deep foaming, foam, and residue-free polar molecules, thus its excellent transmission performance; because of its water-proof, a stable performance so comes with long service life.

Features of physical foaming:

1.Deep foaming and low dielectric constant

2.Low capacitance

3.High transmission speed

4.Low loose

5.Stable structure and long service life.

How to realize PE material foaming(Nitrogen Foaming)

The material used is polyethylene; the manufacturing process of the core wire under the temperature (+ 10 ℃), and then supersonic inject the Nitrogen into the PE materials to form uniform bubbles.

Today skin-foam-skin used in insulating communication cable wires.

The inner layer is a low-density PE, the thickness is about 10μm closely adhered to the conductor

so that does not leave any gap between the two, and petroleum jelly prevent moisture penetration during the destruction of the longitudinal cable characteristics;

Foamed PE layer made substantial mixing from about 1% nucleating after extrusion machine injecting nitrogen form a uniform and closely integrated with the inner layer to avoid bubbles directly with non-continuous conductor adhesion and insulator loose.

Due to the absence of such concerns, the degree of foaming can be increased to 60%; the outer PE layer keeps a smooth appearance.
