Title (EN) COMPOSITION CONTAINING POLYAMIDE FOR COOLANT PIPES
(FR) COMPOSITION À BASE DE POLYAMIDE POUR DES TUYAUX DE LIQUIDE DE REFROIDISSEMENT
Abstract:
(EN) The invention relates to the use of a composition comprising at least one polyamide, at least one of said polyamides being a semi-crystalline copolyamide comprising at least one minority motif resulting from the polycondensation of at least one diamine with at least one polymerised fatty acid, particularly a fatty acid dimer, or at least one diamine dimer with at least one dicarboxylic acid, or at least one amino acid dimer, or the mixtures thereof, as a sealing layer in a pipe containing a coolant.
(FR) La présente invention concerne l'utilisation d'une composition comprenant au moins un polyamide, dont l'un au moins dudit polyamide est un copolyamide semi-cristallin comprenant au moins un motif minoritaire issu de la polycondensation: - d'au moins une diamine avec au moins un acide gras polymérisé, en particulier un dimère d'acide gras, ou - d'au moins un dimère diamine avec au moins un acide dicarboxylique, ou - d'au moins un dimère aminoacide, ou leur mélanges, comme couche d'étanchéité dans un tuyau contenant un liquide de refroidissement.
