Title
(EN) BLEND OF FLUORINE-CONTAINING ELASTOMERS
(FR) MÉLANGE D'ÉLASTOMÈRES CONTENANT DU FLUOR
(JA) 含フッ素エラストマーブレンド物
Abstract
(EN)
Provided is a blend of fluorine-containing elastomers comprising 5-60 wt% of a high-molecular-weight fluorine-containing elastomer having a number average molecular weight Mn (liquid chromatography, a tetrahydrofuran developing solvent, a polymer concentration of 0.5 wt%, a measurement temperature of 35°C) of 3,000,000 or more, 20-80 wt% of a middle-molecular-weight fluorine-containing elastomer having an Mn of 100,000-1,000,000, and 10-50 wt% of a low-molecular-weight fluorine-containing elastomer having a Mn of 7,000-13,000. The blend of fluorine-containing elastomers achieves low hardness and low modulus, as well as an improved rolling processability.

L'invention concerne un mélange d'élastomères contenant du fluor, qui comprend 5-60 % en poids d'un élastomère à haut poids moléculaire contenant du fluor, et dont le poids moléculaire moyen en nombre Mn (chromatographie liquide, solvant de développement tétrahydrofuranne, concentration de polymère de 0,5 % en poids, température de mesure de 35°C) est supérieur ou égal à 3000000; 20-80 % en poids d'un élastomère à poids moléculaire intermédiaire contenant du fluor, et dont la valeur Mn est de 100000-1000000; et 10-50 % en poids d'un élastomère à bas poids moléculaire contenant du fluor, et dont la valeur Mn est de 7000-13000. Ce mélange d'élastomères contenant du fluor présente une faible dureté et un faible module, ainsi qu'une aptitude améliorée au calandrage.
