Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 1. A rotomolding composition comprising: at least 95 percent by weight of a thermoplastic polymer; and from 0.1 to 3 percent by weight of iron oxide lamellae having a purity of at least 99 percent or greater, a hardness in the range of 6 to 6.5 Mohs, and an average aspect ratio (long axis/thickness) in the range of from 2 to 30 and wherein said iron oxide lamella has an average size diameter (long axis) in the range of from 2 to 20 μM; wherein said 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 iron oxide lamellae. 2. The rotomolding composition according to claim 1 , wherein said rotomolding composition is further characterized by having a tensile modulus (2%) improvement of at least 10 percent relative to a similar composition free of said iron oxide lamellae. 3. The rotomolding composition of claim 1 , wherein said thermoplastic polymer is an ethylene based polymer or a propylene based polymer.
