Abstract
Patente de Invenção: "COMPOSIçãO DE ISOLAMENTO PARA UM CABO DE ENERGIA ELéTRICA". Uma composição de isolamento para um cabo de energia elétrica e um cabo de energia elétrica que compreende um condutor circundado por uma camada semicondutora interna, uma camada de isolamento e uma camada semicondutora externa, onde a camada de isolamento consiste na dita composição de isolamento, são divulgados. A composição de isolamento é caracterizada em que o polímero de etileno é um copolímero de etileno multimodal obtido mediante polimerização catalisada por coordenação de etileno e pelo menos uma outra alfa-olefina em pelo menos um estágio, o dito copolímero de etileno multimodal tendo uma densidade de 0,890 a 0,940 g/cm^ 3^, uma MFR~ 2~ de 0,1 a 10 g/10 min, uma MWD de 3,5 a 8, uma temperatura de fundição de no máximo 125<198>C e uma distribuição de comonómero como medida por TREF, de modo que a fração de copolímero eluído em uma temperatura mais alta do que 90<198>C não exceda a 10% em peso, e o dito copolímero de etileno multimodal incluindo uma fração de copolímero de etileno selecionada de (a) um copolímero de etileno de peso molecular baixo tendo uma densidade de 0,900 a 0,950 g/cm^ 3^ e uma MFR~ 2~ de 25 a 500 g/10 min, e (b) um copolímero de etileno de peso molecular alto tendo uma densidade de 0,870 a 0,940 g/cm^ 3^ e uma MFR~ 2~ de 0,01 a 3g/10 min.
