Title (EN) PERFLUOROELASTOMER COMPOSITION AND CROSSLINKED MOLDED ARTICLE MADE BY CROSSLINKING AND MOLDING SAID PERFLUOROELASTOMER COMPOSITION
(FR) COMPOSITION D’ELASTOMERE PERFLUORE, ET ARTICLE RETICULE MOULE OBTENU PAR RETICULATION ET MOULAGE DE LADITE COMPOSITION
Abstract:
(EN) There is provided a crosslinked molded article obtained by crosslinking and molding a perfluoroelastomer composition which comprises no additives causing outgas or generating particles such as carbon black, zinc oxide and proton sponge and is capable of providing a crosslinked molded article having significantly improved tensile strength. The crosslinked molded article is transparent and has satisfactory mechanical properties. The crosslinked molded article is obtained by crosslinking and molding the perfluoroelastomer composition consisting of (A) a perfluoroelastomer having iodine atom and/or bromine atom and comprising 20 to 35 % by mole of a perfluoro vinyl ether unit (a) and 65 to 80 % by mole of a tetrafluoroethylene unit (b), (B) an organic peroxide, and (C) a compound having at least two double bonds in its molecule.
(FR) La présente invention concerne un article réticulé moulé obtenu par réticulation et moulage d'une composition d'élastomère perfluoré qui ne comprend aucun additif générant un dégagement gazeux ou des particules telles que du noir de carbone, de l'oxyde de zinc ou de l'éponge à protons, et qui permet d'améliorer sensiblement la résistance à la traction de l'article moulé. Cet article est transparent et possède des propriétés mécaniques satisfaisantes. Il est obtenu en réticulant et en moulant une composition d'élastomère perfluoré comprenant (A) un élastomère perfluoré portant des atomes d'iode et/ou de brome et comprenant 20 à 35 % en mole d'un motif d’éther perfluorovinylique (a) et 65 à 80 % en mole d'un motif de tétrafluoroéthylène (b), (B) un peroxyde organique, et (C) un composé avec au moins deux doubles liaisons par molécule.
