Abstract:
The instant invention provides a rotomolding composition. The a rotomolding composition comprises at least 95 percent by weight of a thermoplastic polymer; and from 0.1 to 3 percent by weight of metal oxide lamellae; wherein the rotomolding composition is characterized by at least one of the following properties: (a) having a retention at elongation at break of at least 85 percent after 4000 hours of accelerated aging; or (b) having a ductility improvement of at least 50 percent relative to a similar composition free of said metal oxide lamellae
