Abstract[English]
A rotomolding composition and a method of rotational molding are disclosed. The rotomolding composition can include (a) 85 wt. % to 99 wt. %, based on the total weight of the rotomolding composition, of a first particulate polyethylene composition having an average particle size of 300 microns to 1500 microns; and (b) 1 wt. % to 15 wt. %, based on the total weight of the rotomolding composition, of a second particulate polyethylene composition that includes 500 ppm to 5000 ppm, based on the total weigh of the second particulate polyethylene composition, of a transition metal stearate, and at least 100 parts per million (ppm), based on the total weight of the second particulate polyethylene composition, of an antioxidant, where the second particulate polyethylene composition has an average particle size of 300 microns to 1500 microns.[French]
Une composition de rotomoulage et un procédé de moulage rotatif sont divulgués. La composition de rotomoulage peut comprendre (a) 85 % en poids à 99 % en poids, sur la base du poids total de la composition de rotomoulage, d'une première composition de polyéthylène particulaire présentant une taille moyenne de particule de 300 microns à 1 500 microns ; et (b) 1 % en poids à 15 % en poids, sur la base du poids total de la composition de rotomoulage, d'une seconde composition de polyéthylène particulaire qui comprend 500 ppm à 5 000 ppm, sur la base du poids total de la seconde composition de polyéthylène particulaire, d'un stéarate de métal de transition, et au moins 100 parties par million (ppm), sur la base du poids total de la seconde composition de polyéthylène particulaire, d'un antioxydant, la seconde composition de polyéthylène particulaire présentant une taille moyenne de particule de 300 microns à 1 500 microns.
