Abstract

Patente de Invenção: "PROCESSO PARA A FORMAçãO DE ESPUMAS FLEXìVEIS DE PELE INTEGRAL PARTINDO DE CICLOPENTANO DE ALTA PUREZA E MISTURA DO MESMO". é fornecido um processo para a preparação de artigos moldados que contêm poliuretana que têm uma zona periférica comprimida e um núcleo celular. As novas espumas flexíveis de pele integral de acordo com a presente invenção são formadas usando-se um componente agente de sopro de mistura de ciclopentano de alta pureza ou de ciclopentano/sio- ou n-pentano muito estável/homogênea. Os artigos moldados são produzidos por introdução em um molde de uma mistura que compreende: (a) um poliisocianato orgânico e/ou orgânico modificado; (b) pelo menos um composto de peso molecular mais alto que tenha pelo menos dois átomos de hidrogênio reativos, (c) opcionalmente, um agente de extensão de cadeia de peso molecular mais baixo e/ou agente reticulante, (d) um agente de sopro que compreende ciclopentano de alta pureza e (e) um catalisador capaz de formar um artigo moldado que tenha uma zona periférica comprimida e um núcleo celular; e deixando a mesma reagir.
