Abstract
La presente invencion describe artículos moldeados de poliuretano, los cuales se producen haciendo reaccionar poliisocianatos con composiciones de poliol obtenidas por descomposicion química de desechos de poliuretano y/o poliurea en un molde. Las composiciones de poliol empleadas en esta invencion tienen un valor de OH de aproximadamente 100 a aproximadamente 500 mg de KOH/g, un contenido de agua de 0 a aproximadamente 5 % en peso, y una viscosidad a 20 degree C de más de 2,000 centipoises (2,000 mPa.s). Estos artículos moldeados de poliuretano preferiblemente tienen una estructura de emparedado, en la cual el nucleo es de poliuretano, y hay al menos una capa exterior hecha de un material plástico opcionalmente reforzado con fibra. Estos artículos moldeados de poliuretano son utiles en las industrias de fabricacion de vehículos de motor, mobiliario, máquinas y equipo.
