Abstract

PROCESSO PARA A CO-EXTRUSãO DE FLUXOS DE MASSA FUNDIDA DE COMPOSIçãO DIFERENTE. A presente invenção refere-se a um processo para a co-extrusão de pelo menos dois fluxos de massa fundida de composições diferentes, com separação a massa fundida em pelo menos dois fluxos de massa fundida e misturando aditivos em pelo menos um fluxo de massa fundida e ajuntando aos fluxos de massa fundida sob co-extrusão em uma ou várias ferramentas de extrusão. O processo é especialmente adequado para a fabricação de folhas PVB com fita colorida para vitrificações compostas.
