Abstract

L'invention concerne l'industrie des matières plastiques. Elle a pour objet les feuilles de démoulage comprenant une pellicule de matiere thermoplastique se passant de support et revêtue sur une face ou les deux d'une couche de démoulage continue comprenant un interpolymère propre à former une pellicule issue du styrène ou d un de ses dérivés, la ou chaque couche de démoulage ayant une épaisseur qui n'excède pas 0,5 micron. Ces feuilles de démoulage sont préférées pour la fabrication de produits manufacturés moulés en résine de polyester armés de fibres de verre.The invention relates to the plastics industry. It relates to release sheets comprising a film of thermoplastic material dispensing with a support and coated on one or both face with a continuous release layer comprising an interpolymer capable of forming a film resulting from styrene or one of its derivatives. , the or each release layer having a thickness which does not exceed 0.5 microns. These release sheets are preferred for the manufacture of molded articles of polyester resin reinforced with glass fibers.
