Abstract
FORMULAÇÕES DE POLÍMERO E TUBULAÇÃO DE IRRIGAÇÃO INCLUINDO FORMULAÇÕES DE POLÍMERO. Trata-se de modalidades de formulações de polietileno e artigos compreendendo formulações de polietileno. A formulação de polietileno pode incluir de 45 % em peso a 90 % em peso de um MDPE que tem uma densidade de 0,930 g/cm3 a 0,950 g/cm3 e um índice de fusão (I2) de 0,05 g/10 min a 0,5 g/10 min; de 10 % em peso a 50 % em peso de uma composição de polietileno que tem uma densidade de 0,910 g/cm3 a 0,936 g/cm3 e um índice de fusão (I2) de 0,7 g/10 min a 1,0 g/10 min; e de 0,5 % em peso a 5 % de uma composição de lote mestre. A composição de polietileno pode compreender uma área da primeira fração de polietileno em uma faixa de temperatura de 45ºC a 87ºC de um perfil de eluição por meio do método de análise de distribuição de composição de comonômero melhorada (iCCD) e uma área da segunda fração de polietileno em uma faixa de temperatura de 95ºC a 120ºC de um perfil de eluição via iCCD.
