A mixture of a carrier and binder component and polymer powders is provided as a molding composition for sealing rotational molds or for reinforcing selected areas of rotationally molded parts. The carrier and binder component can be very low density polyethylene, petroleum jelly, hydrocarbon wax, hydrocarbon tackifier, or mixtures thereof, and the polymer powders are thermoplastics having a low melt index. The molding composition is applied to selected areas of the rotational mold, such as to the mating flanges of the mold halves to seal the parting line of the mold, or to areas within the mold where it is desired to have reinforced regions of greater wall thickness, such as ribs or bosses.

L'invention concerne un mélange d'un support, d'un composant liant et de poudres de polymère destiné à servir de composition de moulage pour l'étanchéification de moules centrifuges ou afin de renforcer des zones sélectionnées de parties moulées par centrifugation. Le support et le composant liant peuvent être constitués de polyéthylène basse densité, de vaseline, de cire d'hydrocarbonées, d'agent collant hydrocarboné, ou de mélanges de ces produits, et les poudres de polymère sont constituées de thermoplastiques à faible indice de fluage. La composition de moulage est appliquée à des zones sélectionnées du moule centrifuge, notamment aux brides d'appariement des moitiés de moules afin d'étanchéifier la ligne de partage du moule, ou sur des zones à l'intérieur du moule où l'on souhaite obtenir des régions renforcées avec une épaisseur de paroi plus importante, telles que des nervures ou des bosses.
