Aluminum foil Maila: an indispensable shielding material in communication cables

1. Basic concept of aluminum foil Mailla

In the communication cable industry,Al/mylarAs an importantShielding materialWidely used in cable disturbance screens. It is made by compounding soft aluminum foil and polyester film through gravure coating, and then matured before being cut and rolled up. Aluminum foil can be mixed and coated with glue, and after die-cutting, it can be used for assembling shielding and grounding.

2. Types and Applications of Aluminum Foil Mela

There are various types of aluminum foil, including single-sided aluminum foil, double-sided aluminum foil, spread wing aluminum foil, hot-melt aluminum foilAluminum TapeAnd aluminum-plastic composite tape, etc. Aluminum foil, as a key material for aluminum foil, has excellent conductivity, shielding effectiveness, and corrosion resistance, and can adapt to different requirements. Among them, the shielding range is mainly between 100K-3GHz, which can effectively shield external electromagnetic interference.

Among these types, it is particularly important to mention the hot-melt aluminum foil mela. Hot melt aluminum foil is coated with a layer of hot melt adhesive on the side of the aluminum foil in contact with the cable. When preheated at high temperatures, hot melt adhesive can tightly wrap around the cable core wire, enhancing the shielding performance of the cable. In contrast, ordinary aluminum foil has no stickiness and is simply wrapped around the insulation layer of the cable core, resulting in poor shielding performance.

3. Advantages and Applications of Aluminum Foil Mela

Aluminum foil Mylar, as an important component of communication cables, has many advantages, making it the preferred shielding material for users.

1. Good shielding effectiveness

Through the conductivity of the aluminum layer and its absorption of electromagnetic waves, aluminum foil can efficiently shield electromagnetic interference from the outside world. Especially in specific frequency bands, its shielding performance is better applied.

2. Superior anti-corrosion performance

Aluminum foil has good oxidation resistance and corrosion resistance, which can prevent aluminum foil from being corroded during use. This feature enables aluminum foil to work stably for a long time under harsh environmental conditions.

3. Suitable for various types of cables

Due to the wide variety of aluminum foil Mylar and its adjustable adhesive properties, it can be accurately selected and applied according to different cable types and shielding requirements. This provides greater flexibility for manufacturers of different types of communication cables.

4. Case Study: Application of Aluminum Foil Mela in Communication Cables

1. Copper cable shielding

Aluminum foil Mylar is often used in combination with copper shielding in the manufacturing process of communication cables. Copper shielding can provide better shielding effect, while aluminum foil can enhance the corrosion resistance and service life of cables.

2. Optical cable shielding

In the manufacturing of optical cables, aluminum foil Mylar is also widely used in the outer shielding part of optical cables. Aluminum foil Maila provides excellent shielding performance to protect optical cables from external electromagnetic interference.

5. Conclusion

Al/mylarAs an indispensable shielding material in communication cables, it plays an important role in ensuring the stable transmission and anti-interference ability of communication cables. Through excellent shielding effectiveness and corrosion resistance, it can meet shielding requirements in different ranges. In the future, with the continuous development of the communication industry, aluminum foil Mylar is expected to further improve and innovate in terms of performance and application, bringing more possibilities to the communication cable industry.
