CA 2541270

Melt fracture is reduced, without the necessity of polymer processing-aid additives specifically designed to alleviate exit region surface melt fracture phenomenon, by heating at least a portion of the die through which the polymer is extruded. The die exit region is maintained at a temperature above the bulk melt temperature of the polymer extruded through the die exit hole.

Pour réduire les marques de coulée sans recourir à des additifs d'aide au traitement conçus spécifiquement pour atténuer le phénomène de marque de coulée dans la zone de sortie, on chauffe au moins une partie de la matrice par laquelle le polymère est extrudé. La région de sortie de la matrice est maintenue à une température supérieure à la température de fusion du polymère extrudé par cette région.
