Title
(EN) SYNTACTIC POLYURETHANE ELASTOMERS HAVING DISTINCT MORPHOLOGY FOR USE IN SUBSEA PIPELINE INSULATION
(FR) ELASTOMÈRES DE POLYURÉTHANE SYNTACTIQUE AYANT UNE MORPHOLOGIE DISTINCTE POUR L'UTILISATION DANS L'ISOLATION DE CONDUITES SOUS-MARINES
Abstract
(EN)
Syntactic polyurethane elastomers are made using a non-mercury catalyst. The elastomer is made from a reaction mixture containing a polyether polyol, a chain extender, a polyisocyanate and microspheres. The elastomer is characterized morphologically by the presence of small discrete morphological domains 0.1 to 3 μm in diameter, and the substantial absence of discrete morphological domains 5 to 30 μm in diameter. The elastomer adheres well to itself, which makes it very useful as thermal insulation for pipelines and other structures that have a complex geometry.
(FR)
L'invention concerne des élastomères de polyuréthane syntactique fabriqués en utilisant un catalyseur non à base de mercure. L'élastomère est fabriqué à partir d'un mélange de réaction contenant un polyéther polyol, un allongeur de chaîne, un polyisocyanate et des microsphères. L'élastomère est caractérisé morphologiquement par la présence de petits domaines morphologiques distincts de 0,1 à 3 µm de diamètre, et l'absence substantielle de domaines morphologiques distincts de 5 à 30 µm de diamètre. L'élastomère adhère bien à lui-même, ce qui le rend très utile pour l'isolation thermique des conduites et d'autres structures qui ont une géométrie complexe.
