Abstract[English]
When added to a linear polyethylene in relatively small amounts (fewer than about 5,000 parts per million), an ethylene vinyl alcohol copolymer (EVOH) reduces melt defects during extrusion processes, even in the absence of fluoropolymers.[French]
Lorsqu'elle est ajoutée à un polyéthylène linéaire en quantités relativement faibles (moins d'environ 5 000 parties par million), un copolymère d'éthylène-alcool vinylique (EVOH) réduit les défauts de fusion pendant les processus d'extrusion, même en l'absence de polymères fluorés.
