Effective screen based on copper – magnetic composition of fluorosiloxane rubber

Abstract

Currently, the issues of creating effective screens for the laboratory of electromagnetic compatibility, protection of electronic equipment and people from external electromagnetic radiation in the entire frequency range are becoming more and more urgent. We have developed and manufactured a composite screen based on fluorosiloxane rubber with the addition of copper powder (26%) and Mu Metal powder (39%), which at a thickness of 0.25 mm proved to be effective in the spectrum of frequencies from 50 Hz to 28 GHz. This composite screen is flexible and represents an analogue of textile fabric, which can be rolled up, and also has a wide operating temperature range (from -90 to + 250 ℃).
