Abstract

método para produzir uma composição de composto reticulável em condições de alta temperatura e baixo chamuscamento. a presente invenção refere-se a métodos de produção de composições de composto reticulável em condições de alta temperatura, baixo chamuscamento, inclusive sem chamuscamento, que é definido aqui, sendo que o método compreende a combinação por fusão de um fluxo primário a uma temperatura de 120,0° a 150,0 °c, em que o fluxo primário compreende uma ou mais poliolefinas termoplásticas e um ou mais antioxidantes, mas é desprovido de aditivos de cura selecionados a partir do grupo que consiste em: peróxidos e coagentes de reticulação; e injetar no material fundido composto uma combinação de aditivos de cura compreendendo um ou mais peróxidos orgânicos e um ou mais coagentes de reticulação e misturar homogeneamente a uma ou mais poliolefinas termoplásticas, um ou mais antioxidantes, um ou mais peróxidos orgânicos e um ou mais coagentes de reticulação através da combinação por fusão dos mesmos. também são fornecidos métodos para a produção de composições de compostos reticulados e artigos fabricados.
