Abstract

Un método continuo para producir espño.umas de poliamida mediante un proceso de formación de espuma por extrusión. La espuma de poliamida incluye una resina de poliamida combinada con un extensor de cadena mixto que incluye un extensor de cadena de epoxi y una cera de polipropileno injertado con anhídrido maleico (MAPP). Las espumas de poliamida producidas tienen propiedades mejoradas, incluyendo una superficie lisa, baja densidad y un tamaño de celda peque.
