Abstract

La presente invencion se refiere a espumas de poliuretano que tienen alta resilencia y una resistencia al envejecimiento debido a la humedad, significativamente mejorado, las cuales se forman a partir de un diol de polidieno, preferentemente un diol de polibutadieno hidrogenado, que tiene una funcionalidad hidroxilo de 1.6 a 2.0 y a partir de un poliisocianato aromatico que tiene una funcionalidad isocianato de 2.5 a 3.0. El diol de polidieno se mezcla preferentemente con agentes de espumacion o formacion de espuma, antes de la adicion del poliisocianato altamente reactivo.
