Abstract

La presente invencion proporciona un aparato y un proceso para producir una espuma rigida de poliuretano que implica pulverizar una mezcla que contiene al menos un isocianato y al menos un compuesto reactivo con isocianato sobre una superficie de soporte a traves de una pluralidad de boquillas pulverizadoras planas dispuestas sobre la superficie de soporte de manera que las celulas de espuma en la espuma rigida de poliuretano tienen una estabilidad dimensional y resistencia a compresion sustancialmente uniforme en toda la espuma. Las espumas rigidas de poliuretano de la invencion son utiles en un amplio intervalo de aplicaciones tales como para tejados, revestimiento, paneles metalicos tales como los usados en puertas para garajes y similares.
