Abstract

La presente invención se refiere a mejoras en un método para fabricar elastómeros de poliuretano, moldeados por inyección de reacción, reforzados con llenadores inertes en las que dos corrientes son reaccionados una con otra; una corriente contiene poliisocianato y la otra corriente contiene cuando menos un material que a su vez contiene un hidrógeno activo; dichas mejoras están caracterizadas porque comprenden la colocación de todo el llenador inerte en la corriente que contiene el isocianato, antes de mezclarse y reaccionar con la corriente que contiene el hidrógeno activo.
