Abstract
"MESCLAS E FILMES DE POLIETILENO". Uma mescla que compreende um polietileno de média densidade e alto peso molecular (HMW MDPE) e um polietileno linear de baixa densidade (LLDPE) é descrita. A mescla compreende entre cerca de 20% em peso e cerca de 80% em peso de HMW MDPE. O HMW MDPE tem um peso específico entre cerca de 0,92 e cerca de 0,944 g/cm^ 3^, um índice de fusão MI~ 2~ entre cerca de 0,01 e cerca de 0,5 dg/min, e uma relação de fluxo em fusão MFR entre cerca de 50 e cerca de 300. A mescla compreende também entre cerca de 20% em peso e cerca de 80% em peso de LLDPE. O LLDPE tem um peso específico dentro da faixa entre cerca de 0,90 e 0,925 g/cm^ 3^ e um MI~ 2~ dentro da faixa entre cerca de 0,50 e cerca de 50 dg/min. A mescla fornece filmes com tenacidade e resistência ao rasgamento significativamente melhores, comparado com MDPE ou HDPE, e um alto módulo, comparado com LLDPE.
