(EN) ELASTOMERIC COMPOSITION WITH COARSE BLACK
(FR) COMPOSITION ELASTOMERIQUE AVEC NOIR GROSSIER
Abstract
(EN)
The present invention relates to an elastomeric composition comprising a) an elastomeric matrix comprising at least 60 phr of at least one elastomer chosen from natural rubber and synthetic polyisoprenes, b) 10 to 30 phr of a carbon black having a BET specific surface area varying from 15 to 28 m2/g and a COAN index varying from 20 to 60 ml/g, c) at least 10 phr of at least one plasticizer, and d) a crosslinking system.
(FR)
La présente invention concerne une composition élastomérique comprenant a) une matrice élastomérique comprenant au moins 60 pce d'au moins un élastomère choisi parmi le caoutchouc naturel et les polyisoprènes synthétiques, b) 10 à 30 pce d'un noir de carbone présentant une surface spécifique BET variant de 15 à 28 m2/g et un indice COAN variant de 20 à 60 ml/g, c) au moins 10 pce d'au moins un plastifiant, et d) un système de réticulation.
