Abstract

Se describen artículos de espuma de polímeros moldeados que tienen una estructura de espuma novedosa. Los artículos de espuma de polímeros incluyen una matriz polimérica continua que define una pluralidad de neumatoceles en ella los cuales están presentes en la totalidad del artículo. La región superficial además se caracteriza por tener neumatoceles comprimidos. La estructura de espuma novedosa se logra inclusive cuando se moldean artículos de espuma de polímeros que comprenden una forma y un volumen donde una esfera que tiene un diámetro entre 2 cm y 1.000 cm se ajustaría dentro del artículo en al menos una ubicación sin sobresalir de la superficie del artículo, y el artículo además tiene un volumen total de más de 1.000 cm³. También se describen métodos para elaborar espuma de polímeros fundidos estabilizada, y para elaborar un artículo de espuma de polímeros moldeado usando la espuma de polímeros fundidos estabilizada.Molded polymeric foam articles having a novel foam structure are disclosed. Polymer foam articles include a continuous polymer matrix defining a plurality of pneumatoceles therein which are present throughout the article. The superficial region is further characterized by having compressed pneumatoceles. The novel foam structure is achieved even when molding polymer foam articles comprising a shape and a volume where a sphere having a diameter between 2 cm and 1,000 cm would fit within the article in at least one location without protruding from the surface area of the article, and the article also has a total volume of more than 1,000 cm³. Also described are methods for making stabilized molten polymer foam, and for making a molded polymer foam article using the stabilized molten polymer foam.
