Material Notes:

Description: POLASHEET gasketing are composite EMI shielding and weather sealing materials. Either solid or sponge silicone may be specified as the weather seal. In POLASHEET gasketing individual monel or aluminum wires embedded in the silicone and oriented perpendicular to mating flange surfaces provide the EMI shielding. Wires are crimped for resiliency. Solid silicone POLASHEET gasketing is available with high-tack pressure-sensitive adhesive backing. POLASHEET gasketing with solid silicone weather seal are recommended for sealing under high pressure conditions.Information provided by Chomerics
