The EMIAptitude d'un appareil ou d'un système électrique ou électronique, à fonctionner dans son environnement de façon satisfaisante, sans produire lui-même des perturbations électromagnétiques gênantes pour tout ce qui se trouve dans cet environnement et ne pas être non plus perturbé par les autres équipements électrique ou électronique qui l’entourent. More SIL COATING is a silicone-based gasket, foam-expanded or solid (compact), covered with a thin layer (skin) of Silver & Copper with a thickness of 0.15mm. It therefore makes it possible to achieve sealed joints and electrical conductors It has ideal properties in terms of resistance to pressure and aging. It has high conductivity and very high flexibility (20 to 60 shA). The nature of its outer layer allows it a good galvanic compatibility with almost all supports and consequently to avoid corrosion or galvanic couples. Silver is after gold the best electric conductor. The gasket thus made are reusable after disassembly because they do not contain metal particles likely to damage the surfaces in contact. Moreover, the nature of its internal structure makes it an inexpensive gasket compared to standard silicone seals loaded with Silver/ Copper. The same applies to co-extruded gaskets. These gaskets only exist in O-ring shape!… They are easy to install but require a throat.
