Abstract

"PROCESSO PARA PREPARAR CONTAS POLIMéRICAS DE PROPILENO EXPANSìVEIS" Um processo prepara contas poliméricas de propileno expansíveis mediante mistura a massa fundida de propileno com um agente de sopro orgânico volátil e com um agente de nucleação em uma extrusora, após o que a extrusão e a pelotização do extrusado ocorrem em um banho de água sob condições de temperatura e pressão em que praticamente nenhuma espumação das pelotas ocorre.
