Title (EN) FLUOROPOLYMER THERMOPLASTIC ELASTOMER
(FR) ÉLASTOMÈRE THERMOPLASTIQUE À BASE DE FLUOROPOLYMÈRE
Abstract:
(EN) The invention relates to an object or object part made from a composition comprising at least one fluoropolymer F, wherein: - the at least one fluoropolymer F comprises vinylidene fluoride units and at least 30 wt.% of units derived from at least one monomer of formula (I): (I) CX1X2=CX3Y, wherein each of Χ1, X2 and X3 is independently selected from H, CI, F, Br, I and alkyl groups comprising from 1 to 3 carbon atoms which are optionally partly or fully halogenated and Y is an alkyl group comprising from 1 to 3 carbon atoms which is optionally partly or fully halogenated; - the proportion of the at least one fluoropolymer F in the composition is at least 80 wt.%; and - the viscosity of the composition is at least 1000 Pa.s at a temperature of 230°C and at a shear rate of 100 s-1.
(FR) L'invention concerne un objet ou une pièce d'objet réalisé(e) à partir d'une composition comprenant au moins un fluoropolymère F. Selon l'invention : ledit au moins un fluoropolymère F comprend des motifs de fluorure de vinylidène et au moins 30 % en poids de motifs dérivés d'au moins un monomère de formule (I) : (I) CX1X2=CX3Y, chacun des Χ1, X2 et X3 étant indépendamment choisi parmi H, Cl, F, Br, I et des groupes alkyle comprenant de 1 à 3 atomes de carbone qui sont éventuellement partiellement ou totalement halogénés et Y est un groupe alkyle comprenant de 1 à 3 atomes de carbone qui sont éventuellement partiellement ou totalement halogénés ; la proportion dudit au moins un fluoropolymère F dans la composition est d'au moins 80 % en poids ; et la viscosité de la composition est d'au moins 1 000 Pa.s à une température de 230 °C et à un taux de cisaillement de 100 s-1.
