Electromagnetic shielding insulation protective film can effectively reduce electromagnetic interference and signal leakage, and improve the safety and reliability of products

Electromagnetic shielding insulation protective filmIt is an electromagnetic shielding (EMC) insulation protective film applied to electronic products, communication equipment, power equipment, etc. It has good shielding, insulation, radiation resistance and other characteristics, which can effectively reduce electromagnetic interference and signal leakage, improve product safety and reliability.
The following is the basic structure and characteristics of electromagnetic shielding insulation protective film:
Electromagnetic shielding insulation protective film is usually composed of conductive materials (such as aluminum foil, copper wire, etc.), plastics (such as rubber, plastic, etc.), and insulating materials (such as paper, cloth, etc.). Its characteristics are high shielding and radiation resistance, which can effectively reduce electromagnetic interference and signal leakage, and improve the safety and reliability of the product. Electromagnetic shielding insulation protective film has a wide range of applications, including electronic products, communication equipment, power equipment, etc.

1. High Barrier: The insulation protective layer has a very high reflectivity (greater than 90%) for high-frequency electromagnetic waves, greatly reducing signal loss during transmission;
2. Low conductivity: The insulation protective layer has a high refractive index (over 10%) and absorption rate (less than 10%) for low-frequency electromagnetic waves, which can effectively reduce magnetic field energy;
3. Corrosion resistance: The insulation protective layer has good chemical stability and is not easily corroded by media such as acid, alkali, and salt, and can maintain its original performance for a long time;
4. Easy to construct: Easy to form and not limited by shape, easy to install. Types: There are mainly two types on the market, one is single-sided and the other is multi-faceted. Single sided type: Generally made of polyester film as the surface material, with one or several layers of metalized coating on the back. Multi sided: usually composed of one or more layers of metalized coatings of different materials or thicknesses on polyester film. Thickness: The conventional thickness is 0.03mm-1.5mm, and different thicknesses can be selected according to different applications.
In choosingElectromagnetic shielding insulation protective filmWhen selecting, it is necessary to choose according to the specific situation to ensure that the quality and performance of the product meet the requirements. At the same time, it is also necessary to understand relevant technology and market information in order to better choose suitable materials and products. At the same time, it is also necessary to understand relevant standards and regulations in order to better protect one's own safety.
