    Analysis of Die Drool Phenomenon for Metallocene Based Linear Polyolefins

  • Original language description

    With the aim to understand the die drool phenomenon in more detail, the flow at the end of the die has been analyzed theoretically by the Finite Element Method (FEM) employing modified White-Metzner model as the constitutive equation. It has been revealed that the negative pressure occurs at the die lip area which seems to be driving factor for the die drool phenomenon.

    Analýza jevu die drool při vytlačování metalocenových a lineárních polyolefinů

  • Czech description

    S cílem porozumět jevu die drool, oblast výtoku taveniny z vytlačovací hlavy byla analyzována teoreticky metodou konečných prvků. Bylo zjištěno, že je možné tento jev vysvětlit na základě sání (nedativní hodnota tlaku v tavenině)
