Microwave absorber electromagnetic absorber

Wave-absorbing material is a noise-reduction magnetic film made of soft magnetic powder and resin in a certain proportion.It has high permeability and soft sides covered with double-sided tape.Just paste it in the right position and it has excellent noise suppression.


RMS40 series of absorption chip main components by iron based alloy soft magnetic powder and environmental polymer materials through a series of complex production process (iron based alloy soft magnetic powder production material check ingredients crushing and forming tape cutting inspection packaging delivery); Penghui is one of the few China really from the source of magnetic powder production to fast and stable molding, and then to the absorption chip customized processing can complete one-stop enterprises.


RMS40 series electromagnetic wave absorber in 10Mhz-6Ghz has good absorption effect and electromagnetic loss performance, in the ultra-thin thickness can achieve good effect, provide a variety of thickness for customers to choose, without the thickness of the glue with 0.1mm, 0.15mm, 0.2mm, 0.3mm, 0.5mm, 1.0mm, etc., can also be according to the needs of customer products or customer products to solve the problem required thickness for special customization, such as thicker thickness of 1.5mm, 2.0mm, etc.


Penghui electromagnetic wave absorber to solve the advantage of EMI interference is to avoid secondary reflection caused by electromagnetic interference or leakage, the product can mainly be used in laptop, mobile phone, communication cabinet, vehicle equipment, wearable equipment, intelligent equipment, medical equipment, GPS and other electronic equipment internal cavity, chip, flash memory, FPC wiring, battery, components between EMI problems, the electromagnetic wave absorber has good absorption effect, wide absorption frequency, thickness thin cost performance, use and wide range of application.


1. Vacation chip

An electromagnetic wave absorber, as its name implies, absorbs.This kind of material can absorb the electromagnetic signal projected to its surface. This kind of material is generally used in engineering applications, requiring the material of light quality and has, temperature resistance, humidity resistance, corrosion resistance and other properties.


2. Advantages of the electromagnetic wave absorber:

Widespread: the area size can be adjusted according to the demand, more widely used;

Affordable: spend less money to get good quality products;

Enrichment: wave-absorbing material products can correspond to a variety of sizes and shapes.


3. Electromagnetic shielding material

Electromagnetic shielding material can be understood as isolation, which is the signal blocked between two magnetic fields, mainly used to make the shielding material.The shield surrounds the components, circuit, assembly, cables or the whole system to prevent the external diffusion of the interference electromagnetic field and surrounds the receiving circuit, equipment or system to prevent them from being affected by the external electromagnetic field.


4. Advantages of electromagnetic shielding materials: with the continuous innovation of electronic products, the performance requirements of electronic products are higher, faster speed requirements, more compact structure requirements, and so the requirements for electromagnetic shielding materials are also getting higher and higher.


5. Difference between absorbent materials and shielding materials

The main principle of absorbing material and electromagnetic shielding material is not the same, absorbing material is mainly to absorb the electromagnetic wave and transform into other forms of energy loss, electromagnetic shielding material is to block, through the way of reflection to the electromagnetic signal block outside.The main difference between wave-absorbing material and electromagnetic shielding material lies in the application purpose.


Electromagnetic wave absorber materials refer to a class of materials that can absorb electromagnetic wave energy projected on its surface and convert it into heat energy through material consumption. In engineering applications, applying this material to electronic equipment can absorb leaked electromagnetic radiation and achieve the purpose of eliminating electromagnetic interference. In addition to requiring the absorbing material to have a high absorption rate for magnetic waves in a wide frequency band, it is also required to have the properties of light weight, temperature resistance, moisture resistance and corrosion resistance. In recent years, various electronic devices represented by smartphones have been reduced in size and thickness, and various functions such as NFC and contactless power supply have also been developed. As a result, the high integration inside the device is further developed, and the electromagnetic wave absorber material is used to provide a loop for the sympathetic magnetic field through high magnetic flux, which can improve the efficiency.


Application of electromagnetic wave absorber materials

  1. Suppress radiation noise and internal electromagnetic wave interference of electronic devices;
  2. Noise suppression applied in the quasi-microwave range in the system;
  3. Improve the distance of electromagnetic signal recognition, and prevent the interference between the loop antenna and adjacent metal objects;
  4. Communication equipment, office electronics, computers, home appliances and automotive equipment, radar, ETC (electronic non-stop toll collection system), wireless equipment, military applications, etc.


Performance characteristics of electromagnetic wave absorbers

  1. Excellent electromagnetic wave absorber performance in the microwave range;
  2. Ultra-thin, light, flexible and reliable for a wide range of applications;
  3. Good performance in noise suppression with high penetration rate;
  4. High resistance & thermal resistance;
  5. Various shapes & sizes are available upon request.
