CA 2444527

An electrically conductive flexible polyurethane foam comprising a polyurethane and at least one conductive filler dispersed therein in an amount effective to provide EMI/RFI shielding, wherein the polyurethane comprises an isocyanate component to active hydrogen component in a ratio of at most 0.20:1. Preferably, the foam has compression deflection value at 50 % compression of at most about 25 psi, a foam density of at most 0.95 g/cm3 and/or noise shielding effectiveness at a frequency of about 20 to about 1000 MHz of at least about 10 dB.

L'invention concerne une mousse souple de polyuréthanne électroconductrice, comprenant un polyuréthanne et au moins une charge conductrice dispersée à l'intérieur de ce dernier dans une proportion suffisante pour réaliser un blindage EMI/RFI. Le polyuréthanne présente un rapport composant isocyanate/composant hydrogène actif s'élevant au maximum à 0,20:1 environ. De préférence, cette mousse présente une valeur de flexion, pour une compression de 50 %, s'élevant au maximum à 25 psi environ, une masse volumique maximale de 0,95 g/cm?3¿ et/ou une efficacité de réduction du bruit à une fréquence comprise entre environ 20 et environ 1000 MHz d'au moins 10 dB environ.
