Title
(EN) BLOW MOLDING COMPOSITION
(FR) COMPOSITION POUR MOULAGE PAR SOUFFLAGE
Abstract
(EN)
A blow moldable thermoplastic composition which comprises a blend of a thermoplastic resin, a viscosity modifier which results in the composition having a melt flow rate value of from 1 to 50 grams per 10 minutes, and a weld improvement additive comprising a mixture of a high molecular weight multifunctional nitrogen containing hindered phenolic antioxidant and a high molecular weight multifunctional ester group-containing hindered phenolic antioxidant.
(FR)
Cette invention concerne une composition thermoplastique pouvant être moulée par soufflage, laquelle comprend un mélange des éléments suivants: une résine thermoplastique; un modificateur de viscosité qui confère à la composition une valeur d'écoulement à l'état fondu de 1 à 50 grammes par 10 minutes; et un additif d'amélioration de soudure. Ce dernier se compose d'un mélange comprenant, d'une part, un antioxydant phénolique inhibé, multifonctionnel, contenant de l'azote et ayant un poids moléculaire élevé et, d'autre part, un antioxydant phénolique inhibé, multifonctionnel, contenant un groupe ester et ayant un poids moléculaire élevé.
