Abstract

L'invention concerne des garnitures d'étanchéité résistant à la corrosion et formant un blindage électromagnétique. Les garnitures selon l'invention comprennent une âme de matière plastique chargée de particules métalliques, et une enveloppe 20-2 d'un polymère isolant qui est traversée par les particules métalliques de l'âme lorsque la garniture est serrée entre deux surfaces métalliques. Application à l'étanchéité des guides d'ondes des radars.The invention relates to gaskets resistant to corrosion and forming an electromagnetic shield. The gaskets according to the invention comprise a core of plastic material loaded with metallic particles, and a casing 20-2 of an insulating polymer which is traversed by the metallic particles of the core when the lining is clamped between two metal surfaces. Application to the sealing of radar waveguides.
