Abstract
"ESPUMA DE POLìMERO TREMOPLáSTICO CELULAR E PROCESSO PARA SUA PREPARAçãO" São providas espumas de polímero termoplástico tendo propriedades de amortecimento de ruído satisfatórias para aplicações exigentes e que apresentam resistência mecânica, sendo de fabricação económica e hidroliticamente estáveis. Métodos para preparar essas espumas são também providos. As espumas são úteis no controle de ruídos, almofadas, filtração e absorção de fluido e exibem uma ou mais das seguintes propriedades: 1). tamanho médio de célula maior que cerca de 2mm; 2). estrutura substancialmente de célula aberta e 3). poros relativamente grandes conectando as células. Para que as espumas sejam acusticamente ativas, a espuma deve possuir uma estrutura substancialmente de célula aberta e uma resistividade a fluxo de ar relativamente baixa. Espumas com estrutura substancialmente de célula aberta e resistividade a fluxo de ar relativamente baixa são preparadas abrindo-se mecanicamente uma espuma que tem um tamanho médio de célula maior que cerca de 2mm. Na maioria dos casos, essa abertura mecânica cria poros relativamente grandes conectando as células.
