Abstract

Los artículos de elastomeros de poliuretano formados a partir de mezclas prepoliméricas tienen un contenido de disocianato de difenilmetano libre (MDI) desde 2,0 hasta 5,0 % en peso, basado en el peso de la mezcla prepolimérica. Las mezclas prepoliméricas contienen un prepolímero de poliéster, poliéter, o policaprolactona (PCL) y MDI. Los artículos de elastomeros de poliuretano se forman curando la mezcla prepolimérica con un diluente de cadena, tal como un agente curativo que comprende un complejo de metilen dianilina-cloruro de sodio. Los artículos tienen buenas propiedades físicas que pueden pesar por encima de 225 kg, y tener un espesor de tres ejes mayor que 10,2 cm.
