Abstract[English]
An additive preblend for production of cap and closure grade polypropylene comprises a mixture of low melting temperature additives and higher melting temperature additives. Inclusion of the higher melting temperature additives eliminates dusting, bridging, and choking issues encountered when adding the lower melting temperature additives separately to a screw feeder for a polypropylene extruder.[French]
L'invention concerne un prémélange d'additifs pour la production de polypropylène et de polypropylène pour bouchons et fermetures qui comprend un mélange d'additifs à faible point de fusion et d'additifs à point de fusion plus élevé. L'inclusion des additifs à point de fusion plus élevé élimine les problèmes de poudrage, de pontage et d'obstruction rencontrés lors de l'ajout des additifs à point de fusion inférieur séparément dans un dispositif d'alimentation à vis d'une extrudeuse de polypropylène.
