For Wave Absorbing & Shielding Materials


Electromagnetic pollution has become the main physical pollution of ecological environment in 21st century. At present, to limit the development of electromagnetic pollution, many countries and international organizations have successively established various laws and regulations of preventing electromagnetic interference.

Seeing from the measures of restricting electromagnetic radiation and leakage, using absorbing and shielding materials is an effective way. For high frequency microwave section, our SR-B absorbing material has excellent wave absorption performance within 2-10 GHZ frequency, and has been widely used now.
