Abstract

Procedimiento para llenar mezclas de reacción para materiales espumados de un solo componente en botellas de presión, donde la mezcla de reacción, compuesta como mínimo de dos componentes de reacción y de un agente de propulsión, se forma en un cabezal mezclador de inyección y se llena en botellas de presión evacuadas, dotadas de una válvula, caracterizado porque directamente después del llenado de la botella de presión con la mezcla de reacción se dosifica agente de propulsión puro a través del cabezal mezclador de inyección.
