Abstract

La presente descripción está dirigida a una estructura de espuma de múltiples capas continua, reticulada físicamente, que comprende al menos una capa de polipropileno/polietileno de espuma con una capa protectora de TPU. La estructura de espuma de múltiples capas se puede obtener co-extruyendo una estructura de múltiples capas que comprende al menos una capa de composición de espuma con al menos una capa de composición protectora, irradiando la estructura co-extruida con radiación ionizante y espumando continuamente la estructura irradiada.
