Abstract

Patente de Invenção: <B>"MISTURA DE POLIóIS, SISTEMA DE MúLTIPLOS COMPONENTES PARA A PRODUçãO DE ESPUMA DE POLIURETANO, E ESPUMA PRODUZIDA PELO MESMO"<D>. Uma mistura de polióis é divulgada para a preparação de espumas de poliuretano. A mistura inclui um primeiro poliol tendo uma funcionalidade de cerca de 2, um número de hidroxila variando de cerca de 20 a cerca de 90, e um peso equivalente variando de cerca de 600 a cerca de 2800; um segundo poliol tendo uma funcionalidade variando de cerca de 4 a cerca de 8, um número de hidroxila variando de cerca de 200 a cerca de 600, e um peso equivalente variando de cerca de 90 a cerca de 280; e um terceiro poliol tendo uma funcionalidade variando de cerca de 2,5 a cerca de 4, um número de hidroxila variando de cerca de 15 a cerca de 500, e um peso equivalente variando de cerca de 180 a cerca de 4000. A mistura de polióis é capaz de reagir com um composto de isocianato, na presença de água, para produzir uma espuma tendo uma densidade variando de cerca de 8,00923169 a cerca de 80,0923169 kg/m³ (0,5 a 5 libras/pés), uma resistência à compressão variando de cerca de 20,68427188 a cerca de 137,8951459 kPa (3 a 20 psi), e um fluxo de ar variando de cerca de 10 a cerca de 1000 cm³/minuto.
