Patent

CA 2623543

The invention relates to the use of a rubber compound wherein the mechanical properties thereof are improved. In particular, the rubber compound has increased elongation at rupture and/or increased tensile strength and/or increased tear strength, and a reduced permanent set (DVR). The rubber compound comprises a rubber (A) having at least two functional groups which can be cross-linked by hydrosilylation, a cross-linking agent comprising hydrosiloxane or hydrosiloxane derivative or a mixture of several hydrosiloxanes or derivatives, which comprise at least two SiH-groups per molecule in the centre, a hydrosilylation catalyst system (C), at least one filling material (D) and a coagent (E) which can be cross-linked by hydrosilylation, for use as a material in the insertion area of the fuel cells.

La présente invention concerne l'utilisation d'un composé de caoutchouc dont les caractéristiques mécaniques sont améliorées. Ce composé de caoutchouc doit notamment présenter un meilleur allongement à la rupture et/ou une meilleure résistance à la traction et/ou une meilleure résistance à la propagation du déchirement, avec un écart permanent réduit. Afin d'utiliser ce composé comme matériau dans le domaine des piles à combustible, le composé de caoutchouc comprend un caoutchouc (A) présentant au moins deux groupes fonctionnels réticulables par hydrosilylation, un agent de réticulation (B) constitué d'hydrosiloxane, d'un dérivé d'hydrosiloxane ou d'un mélange de plusieurs hydrosiloxanes ou dérivés d'hydrosiloxane qui présentent dans le milieu au moins deux groupes SiH par molécule, un système catalyseur d'hydrosilylation (C), au moins une charge (D), ainsi qu'au moins un coagent (E) réticulable par hydrosilylation.
