Abstract

"PROCESSO PARA A MOLDAGEM POR COINJEçãO DE UM ARTIGO DE VáRIAS CAMADAS, ARTIGO DE VáRIAS CAMADAS, E, PROCESSO PARA A COEXTRUSãO DE UM ARTIGO DE VáRIAS CAMADAS" Processo para a moldagem por coinjeção de um artigo de várias camadas, que compreende coinjetar em uma temperatura selecionada (i) uma primeira camada de resina de polímero externa tendo uma viscosidade na temperatura de coinjeção selecionada, e (ii) uma segunda camada de resina de polímero interna tendo uma viscosidade na temperatura de coinjeção selecionada, em que a razão da viscosidade da resina de polímero externa para a viscosidade da resina de polímero interna na temperatura de coinjeção é inferior a, ou igual a, cerca de 2 e a temperatura de coinjeção está acima da temperatura de fusão da resina em fusão mais elevada e abaixo da temperatura de degradação da resina de degradação mais baixa para formar um artigo de várias camadas. Um processo para a coextrusão é também provido.
