Characteristics of Microwave Absorbing Powder Products
Made by special powder metallurgy and chemical surface coating processes on iron-based raw materials or micrometer sized alloy powders, it has the characteristics of low dielectric, high magnetic loss, and good impedance matching. It is suitable for electromagnetic shielding and absorption materials in the range of 0.5GHZ-18GHZ, such as coating, patch, casting, and absorbing putty.
