POLYESTER FILM CONTAINING FINE CELLS
A polyester film containing fine cells is obtained by extrusion-molding into sheet a composition comprising aromatic polyester, 3 to 20 wt %, based on the polyester, of crystalline polypropylene having a melt-flow index of 0.2 to 120, and 0.001 to 3 wt %, based on the sum of the amount of the polyes...

| description | A polyester film containing fine cells is obtained by extrusion-molding into sheet a composition comprising aromatic polyester, 3 to 20 wt %, based on the polyester, of crystalline polypropylene having a melt-flow index of 0.2 to 120, and 0.001 to 3 wt %, based on the sum of the amount of the polyester and that of the polypropylene, of a surfactant, and stretching the sheet in at least one direction. Since this polyester film contains innumerable fine closed cells, it has a small apparent specific gravity and shows a large hiding power when titanium oxide is added thereto in only a small amount or even not added, thus being preferably utilized as base materials for various products in plate-making or information industry.
Une pellicule en polyester contenant des cellules infimes est obtenue en moulant une feuille par extrusion avec une composition comprenant du polyester aromatique, entre 3 et 20 % en poids du polyester d'un polypropylène cristallin ayant un indice de fusion et de coulée compris entre 0,2 et 120, et entre 0,0001 et 3 % en poids du polyester et du polypropylène additionnés d'un agent tensio-actif. On étire ensuite la feuille dans au moins une direction. Comme cette pellicule en polyester contient d'innombrables cellules fermées infimes, elle a une gravité spécifique apparente réduite et a une grande puissance d'occultation lorsque l'on n'y ajoute une quantité minime d'oxyde de titane, ou même lorsque l'on y ajoute rien. On l'utilise donc de préférence comme matériau de base de différents produits de l'industrie informatique ou de fabrication de plaquettes. |
