Product Description Absorbing materials refer to a type of functional material that can absorb and attenuate the energy of electromagnetic waves incident in space, and reduce or eliminate reflected electromagnetic waves. They are generally composed of a matrix material and a loss medium. Absorb and consume the energy of Weibo through small polar molecules. According to the propagation law of electromagnetic waves in the medium from low magnetic to high magnetic permeability directions, high magnetic permeability ferrite is used to guide electromagnetic waves. Through resonance, a large amount of radiation energy of electromagnetic waves is absorbed, and then the energy consumed by electromagnetic waves is transformed into thermal energy through coupling.Electromagnetic waves induce current in materials, and the transmission of current inside the material is hindered, resulting in decay and conversion into internal energy. The higher the conductivity, the greater the macroscopic current caused by charge carriers (current caused by electric field and eddy current caused by magnetic field), which is conducive to the transformation of electromagnetic energy into thermal energy.The absorbing material is mainly a shielding film based on ferrite as the substrate. Its main function is to absorb and couple electromagnetic waves to prevent the superposition of electric waves, eliminate excess electric waves in intelligent electronic systems, cut and shape the absorbing material, and attach it to the back of the touch panel or ribbon cable to resist electromagnetic interference and optimize the performance of the touch screen. Principles of absorbing materials1. The principle of absorbing materials is to use magnetic microwave absorbers as the main body to convert the electromagnetic waves of electronic devices into thermal energy through insulation loss, magnetic loss, and resistance loss, in order to reduce electromagnetic radiation. It has the characteristics of high permeability, selectable frequency band width, and can be developed specifically for specific frequency bands.2. Absorbing materials have good absorption characteristics in the range of 10MHz~6GHz, which can avoid electromagnetic interference or leakage caused by secondary reflection. The main types of products are absorption patches, which can also be processed into various shapes according to customer needs. Absorbing materials can be used inside the cavities of electronic devices such as laptops, mobile phones, and communication cabinets.Various shapes such as round, square,strip shape, fillet rectangle,ellipse,trapezoidal,rectangular and irregular can be customized.3. Absorbing materials have good electromagnetic wave absorption effect, wide absorption frequency, and can be customized according to customer requirements in the frequency band. They have thin thickness, high cost-effectiveness, and a wide range of uses and applications.FAQ Q1,Are you trading company or manufacturer?
