Beschreibung
Zusammenfassung:	Disclosed is a colored high density polyethylene composition. The composition comprises a high density polyethylene, phthalocyanine blue, and talc. The composition exhibits reduced warpage in molded articles compared to those which do not contain talc. The composition is useful for injection molding and many other applications where a blue color is needed and low warpage is desired. L'invention concerne une composition de polyéthylène haute densité colorée. La composition comprend un polyéthylène haute densité, du bleu de phtalocyanine et du talc. La composition présente un gauchissement réduit dans des articles moulés par comparaison à ceux qui ne contiennent pas de talc. La composition est utile pour le moulage par injection et pour de nombreuses autres applications dans lesquelles une couleur bleue et un faible gauchissement sont souhaités.
