With the development of electronic products, thin and light has become the requirements of The Times, while RFID anti-metal readers and their labels, EMI electronic components, wireless charging products and electromagnetic screens have put forward the same requirements, in order to solve this problem, absorbing materials came into being, in the field of electronic products play an important role. The product is easy to cut, ultra-thin, soft, can be made into rolls or slices according to customer requirements, and can be fitted with shielding materials (metal foil or fabric).
【 Product thickness 】 0.03~0.1mm
Material definition
Wave-absorbing material refers to a class of materials that can absorb the electromagnetic wave energy projected on its surface. According to the material loss mechanism can be divided into resistance type, dielectric type and magnetic medium type. The absorbing material produced by HFC is a magnetic medium type absorbing material.
