Abstract

La presente invencion describe compuestos (elementos tipo emparedado) que tienen un nucleo de poliuretano y al menos una capa de revestimiento e un material plástico reforzado con fibra, los cuales se producen a partir de (a) un nucleo de poliuretano que es el producto de reaccion de un poliisocianato con una composicion de poliol obtenida por descomposicion química de desechos de poliuretano y/o poliurea, y que tiene un numero de OH en el intervalo desde 100 a 500 mg de KOH/g, un contenido de agua desde 0 a 5 % por peso, y una viscosidad mayor de 2,000 centipoises (2,000 mPa.s) (20 degree C) y (b) al menos una capa de revestimiento de un material plástico reforzado con fibras naturales. Estos compuestos sonutiles en la construccion de vehículos de motor, construccion de mobiliario, construccion de máquinas y la construccion de aparatos. Estos preferiblemente se usan en la construccion de vehículos de motor, en particular, como piezas moldeadas en el interior del vehículo de motor.
