Cable Shielding Materials Manufacturers

Aluminum-polyester composite tape is widely used in cable industry and is often used as shielding material for cable. The aluminum-polyester composite tape is composed of aluminum foil and polyethylene or PET polyester. It has good electromagnetic shielding performance and cable appearance effect, which can effectively isolate signal interference inside the cable and electromagnetic wave interference outside, and improve the transmission quality of the cable. At the same time, the aluminum-polyester composite tape also has excellent properties such as waterproof, moisture-proof and corrosion resistance, which can protect the conductors and insulating materials inside the cable from the influence of the external environment. Therefore, in the process of cable manufacturing and maintenance, aluminum-polyester composite tape is widely used in cable shielding, protection and repair.

Factors influencing the shielding effect of aluminum polyester composite tape
Thickness and conductivity of aluminum foil: the thickness and conductivity of aluminum foil will directly affect the shielding effect of aluminum pet polyester composite tape. Generally speaking, the larger the thickness of aluminum foil and the better the conductivity, the better the shielding effect.
Thickness and quality of polyethylene pet polyester : the thickness and quality of polyethylene pet polyester will also affect the shielding effect of aluminum pet polyester composite tape. Generally speaking, the greater the thickness and quality of polyethylene pet polyester , the better the shielding effect.

The joint and grounding mode of the aluminum pet polyester composite tape: the joint and grounding mode of the aluminum pet polyester composite tape will also affect the shielding effect, and the appropriate way should be selected to ensure the optimal shielding effect.
The installation mode and position of the aluminum pet polyester composite tape: the installation mode and position of the aluminum pet polyester composite tape will also affect the shielding effect. It should be installed in accordance with the requirements of the specification to ensure that the position of the aluminum pet polyester composite tape in the cable is reasonable to achieve the best shielding effect.
aluminum pet polyester composite tape is usually used in power cables, communication cables, control cables, coacial cable ,signal LAN cables (CAT 5,CAT6,CAT7 )and other fields. In these types of cables, aluminum pet polyester composite tape can be used to shield, ground, and protect the cable from interference and damage. In addition, aluminum pet polyester composite tape can also be used for cable protection in high temperature, high pressure, high frequency and other special environment.
The thickness of the foil Mylar tape is generally between 0.03mm and 0.07mm, with common thicknesses of 0.04mm, 0.05mm and 0.06mm. Aluminum foil Mylar tape is a kind of cable supporting material with excellent material and stable performance, which can well protect the cable from interference and damage, but also has good anti-corrosion performance, so it has been widely used in the cable industry. It should be noted that different thicknesses of aluminum foil Mylar tape have different shielding effects when used, so the appropriate thickness should be selected according to the special needs of the cable
