This Cem composite seal is IP 68. It is made of metal canvases and expanded sheets impregnated with silicone. It is highly electrically conductive and has very good resilience for environmental 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/RFI applications. It is relatively hard and therefore very resistant to tearing. It is at the same time «elastic». It provides an economic response to the gasket of «flat surfaces» because it ensures a very good sealing to pressure and fluids. It is particularly suitable for small thin joints like MIL connectors. The surface irregularities should not exceed 0.10 mm for the use of this gasket. It is especially prescribed in all military applications that require excellent electrical conductivity and low electrical resistance. A fluor-silicone version is available for use with fuels, oils, hydraulic fluids or other contaminants.
