(FR) ÉLASTOMÈRE DE POLYURÉTHANE SYNTACTIQUE À BASE DE PRÉPOLYMÈRE À SEGMENTS SOUPLES ET CATALYSEUR SANS MERCURE DESTINÉ À ÊTRE UTILISÉ DANS L'ISOLATION DE PIPELINE SOUS-MARIN
Abstract
(EN)
Syntactic polyurethane elastomers are made using a non-mercury catalyst. The elastomer is made from a reaction mixture containing a prepolymer made from a polyether polyol and a polyisocyanate, 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)
L'invention concerne des élastomères de polyuréthane syntactiques fabriqués au moyen d'un catalyseur sans mercure. L'élastomère est obtenu à partir d'un mélange de réaction contenant un prépolymère conçu à partir d'un polyol de polyéther et d'un polyisocyanate, d'un allongeur de chaîne, d'un polyisocyanate et de microsphères. L'élastomère adhère bien sur lui-même, ce qui le rend très utile comme isolant thermique pour des pipelines et autres structures qui présentent une géométrie complexe.
