Abstract

"ESPUMAS DE POLIURETANO DE BAIXA DENSIDADE SOPRADAS COM CO~ 2~, PROCESSO PARA SUA OBTENçãO E ARTIGO OBTIDO". é divulgado um método para preparar uma espuma de baixa densidade soprada com CO~ 2~ tendo um alto teor de células fechadas. Espumas preparadas pelo método da presente invenção são úteis em aplicações de despejamento in loco tais como portas de garagens, câmaras frigoríficas, geladeiras portáteis, refrigeradores, e aquecedores d'água, por exemplo. O uso do método descrito aqui reduz o vazamento de espuma do molde durante as operações de despejamento in loco, e assim reduz o desperdício e o custo associado com a produção de artigos enchidos com espuma feitos usando um procedimento de despejamento in loco.
