Abstract

La presente invención corresponde a nuevas composiciones elastoméricas vulcanizables para componentes de neumáticos, que comprenden fibras de silicato modificado como rellenos. Las fibras de silicato se modifican de acuerdo con el proceso con pH controlado de la invención. Además, la invención se refiere a componentes de neumáticos, que comprenden materiales elastoméricos que se pueden obtener mediante vulcanización de dichas composiciones, y neumáticos para vehículos que comprenden uno o más de dichos componentes. Los materiales elastoméricos vulcanizados según la invención se caracterizan por buenas propiedades mecánicas estáticas y dinámicas, en especial histéresis particularmente baja. Favorablemente, los neumáticos de la invención que comprenden uno o más de dichos componentes tienen una resistencia a la rodadura limitada.
