Title
(PT) composição de mistura de polietileno, filme soprado, artigo e dispositivo recipiente
Abstract
(PT)
composição de mistura de polietileno, filme soprado, artigo e dispositivo recipientea presente invenção provê uma composição de mistura de polietileno apropriada para filme soprado, método para sua produção e filmes fabricados com a mesma. a composição de mistura de polietileno apropriada para filme soprado, de acordo com a presente invenção, compreende o produto de mistura sob fusão de (a) uma quantidade igual ou menor que 4 por cento em peso de um polietileno de baixa densidade (ldpe) tendo uma densidade na faixa de 0,915 a 0,935 g/cm3 e um índice de fusão (i2) na faixa de mais de 0,8 a um valor igual ou menor que 5g/10 minutos, e uma distribuição de peso molecular (mw/mn) na faixa de 6 a 10; (b) 90 por cento ou mais em peso de um polietileno linear heterogêneo de baixa densidade (hlldpe) com uma densidade na faixa de 0,917 a 0,950 g/cm3, e um índice de fusão (i2) na faixa de 0,1 a um valor igual ou menor que 5 g/10 minutos; (c) opcionalmente um agente neutralizante à base de hidrotalcita; (d) opcionalmente um ou mais agentes nucleantes; e (e) opcionalmente um ou mais antioxidantes. quando dita composição de mistura de polietileno é formada em um filme via processo de filme soprado, a taxa de produtividade é melhorada em pelo menos 6 por cento em relação a um polietileno linear de baixa densidade similar. 1/1
