Flexible absorbent material is the product of the expansion of absorbing materials. It appeared with the rise of electric power and telecommunication technology, and its application range is extremely wide.
Flexible absorbent material In the fields of electricity, information technology, automobiles and other supporting fields, the most important thing is that flexible absorbing materials are the main raw materials for the production of electronic components, which brings far-reaching demand. In electronic equipment, the high-frequency noise generated by flat-panel lines will have an unstable impact on the system. The limited circuit board area is wide and it is flat. It is impossible to install a filter. At this time, use flexible absorbent material to cover the entire interference surface forming absorption heat conversion.
