Abstract

Los artículos de espuma polimérica moldeado se describen como que tienen una nueva estructura de espuma. Los artículos de espuma polimérica incluyen una matriz polimérica continua que define una pluralidad de neumatoceles en la misma que está presente en la totalidad del artículo, incluso en la región superficial que se extiende 500 micras debajo de la superficie del artículo. La región superficial se caracteriza, además, por tener neumatoceles comprimidos. La nueva estructura de espuma se logra incluso cuando se moldean artículos de espuma polimérica que comprenden un grosor de más de 2 cm, un volumen de más de 1000 cm3 ; o ambos con un volumen de más de 1000 cm3 y un grosor de más de 2 cm. También se describen los métodos para fabricar los artículos de espuma polimérica moldeados.
