Abstract

Una junta estanca expansible, union sellada y método mejorados de formar una union sellada que incluye una junta estanca que tiene al menos 5% en peso de grafito no expandido o sin exfoliar. El material de grafito es preferiblemente una mezcla de grafito expandido y no expandido comprimido en una hoja u otra forma fijada a una chapa metálica. La composicion preferida es de 5 a 70% en peso de grafito no expandido y de 30 a 95% de grafito expandido, donde el porcentaje de grafito no expandido se controla para proporcionar la expansion deseada de la junta estanca. Una composicion más preferida incluye al menos 10% en peso de grafito no exfoliado o más preferiblemente de 15 a 50% en peso. La junta estanca se coloca entre las superficies a sellar y se fija en posicion. Cuando la union se calienta, el grafito no expandido se exfolia, haciendo que la junta estanca se hinche o expanda, cerrando herméticamente la union. La junta estanca expansible de esta invencion es especialmente adecuada para aplicacion en automocion, incluyendo las juntas estancas de culata y escape que están sometidas a temperaturas superiores a aproximadamente 400 degree C.
