Title
(EN) PULVERULENT MIXTURE OF PRECROSSLINKED NITRILE RUBBERS
(FR) MÉLANGE PULVÉRULENT DE CAOUTCHOUCS NITRILE PRÉRÉTICULÉS
Abstract
(EN)
What are provided are pulverulent mixtures based on specific nitrile rubbers and at least one separating agent, and also a process for producing vulcanizable mixtures and vulcanizates made from these pulverulent mixtures, and the resultant vulcanizates and their use, especially in tyre treads, where an improvement in wet skid resistance, dry grip and rolling resistance delivers is observed with simultaneously good mixing characteristics.
(FR)
L'invention concerne des mélanges pulvérulents à base de caoutchoucs nitrile spécifiques et d'au moins un agent de séparation, ainsi qu'un procédé de production de mélanges vulcanisables et de vulcanisats fabriqués à partir de ces mélanges pulvérulents, et les vulcanisats obtenus et leur utilisation, en particulier dans des bandes de roulement de pneus, une amélioration de la résistance au glissement humide, de l'adhérence sur route sèche et de la résistance au roulement étant observée simultanément à des caractéristiques de mélange satisfaisantes.
