Title
(EN) CAVITY SEALING ARTICLE AND METHOD
(FR) ARTICLE ET PROCEDE PERMETTANT DE FERMER UNE CAVITE
Abstract
(EN)
A planar cavity sealing article comprises: (a) at least one driver comprising a cross-linked foamable polymer, and (b) a sealer comprising an uncross-linked foamable polymer in intimate contact with the at least one driver and substantially surrounding the at least one driver in the plane of the article
(FR)
Un article d'obturation de cavité plane est constitué (a) d'au moins un agent d'activation comprenant un polymère réticulé pouvant mousser, et (b) d'un matériau d'obturation comprenant un polymère non réticulé pouvant mousser qui se trouve en contact intime avec le ou les agents d'activation et qui entoure sensiblement le ou les agents d'activation dans le plan de l'article.
