RFI (Radio Frequency Interference) and EMI (Electromagnetic Interference) - Shielding and Absorbing Materials are specialized products designed to protect electronic devices from unwanted electromagnetic interference and radio frequency interference. These materials function by either reflecting or absorbing electromagnetic radiation, ensuring that sensitive components within electronic devices operate without disruption from external or internal electromagnetic noise. Common applications include use in consumer electronics, telecommunications, and aerospace, where precision and reliability are critical. The main characteristics of these materials include high electromagnetic shielding efficiency, durability, and suitability for various environmental conditions. Prominent manufacturers in this field include companies like Laird Technologies, 3M, and Parker Chomerics.
