Abstract

artigos de espuma polimérica e métodos de produção de espumas poliméricas. os artigos de espuma polimérica moldada são descritos como tendo uma estrutura de espuma inovadora. os artigos de espuma polimérica incluem uma matriz polimérica contínua que define na mesma uma pluralidade de pneumatoceles que está presente em todo o artigo. a região de superfície é adicionalmente caracterizada como tendo pneumatoceles comprimidas. a estrutura de espuma inovadora é alcançada mesmo durante a moldagem de artigos de espuma polimérica que compreendem um formato e um volume em que uma esfera que tem um diâmetro entre 2 cm e 1000 cm caberia dentro do artigo em pelo menos um local sem se projetar a partir de uma superfície do artigo, e artigo tem adicionalmente um volume total de mais de 1000 cm3. também são descritos métodos de produção de uma espuma polimérica fundida estabilizada e de produção de um artigo de espuma polimérica moldado com o uso da espuma polimérica fundida estabilizada.
