Title
(EN) SYNTACTIC POLYURETHANE ELASTOMERS BASED ON LOW UNSATURATION POLYOLS FOR USE IN SUBSEA PIPELINE INSULATION
(FR) ÉLASTOMÈRES DE POLYURÉTHANE SYNTACTIQUE À BASE DE POLYOLS FAIBLEMENT INSATURÉS DESTINÉS À ÊTRE UTILISÉS DANS L'ISOLATION DE CANALISATIONS 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 having a low amount of terminal unsaturation, a chain extender, a polyisocyanate and microspheres. 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)
Les élastomères de polyuréthane syntactique sont préparés à l'aide d'un catalyseur exempt de mercure. L'élastomère est préparé à partir d'un mélange réactionnel contenant un polyéther polyol comprenant une faible proportion d'insaturations terminales, un allongeur de chaîne, un polyisocyanate et des microsphères. L'élastomère adhère bien à lui-même, ce qui le rend très utile pour l'isolation thermique de canalisations et d'autres structures présentant une géométrie complexe.
