Abstract
Un procedimiento para preparar una espuma de poliuretano semi-flexible, que tiene una estructura de celdillas abiertas , haciendo reaccionar juntos un poliéter, agua, un catalizador para la reacción entre grupos isocianato e hidroxilo, y un poli isocianato, caracterizado por formar una mezcla de reacción que incluye, sobre una base de partes en peso, 100 partes de poliéter que contiene al menos 50% de grupos terminales hidroxilo primarios, por fundición, y que tiene un peso equivalente por grupo hidroxilo de aproximadamente 300 a aproximadamente 2000, aproximadamente 5 a aproximadamente 90 partes de un material aniláceo aproximadamente 2 a aproximadamente 5 partes de agua, aproximadamente 0,1 a aproximadamente 2 partes de dicho catalizador y un poli isocinato orgánico aromático que tiene una funcionalidad de aproximadamente 2 a aproximadamente 2,4 siendo la cantidad de dicho poliisocinato suficiente para proporcionar un índice de isocianato, teniendo en cuenta todos los equivalentes de hidrógeno reactivo en la mezcla de reacción, de aproximadamente 80 a aproximadamente 150.
