Radiopaque animal chew
View Patent ↗An animal chew toy comprising a radiopaque polymer. The radiopaque polymer may comprise a polymer that is inherently radiopaque or a polymer that has been made radiopaque by the addition of an additive that provides radiopaque characteristics. The radiopaque polymers of the present invention may be manufactured by melt processing techniques, such as extrusion, compression and/or injection molding.
1. An animal chew toy capable of providing x-ray detection comprising a starch host polymer material and a radiopaque additive wherein the additive consists essentially of a mixture of barium sulfate, calcium carbonate and silica formed into an animal chew toy, wherein said mixture comprises 93-99% by weight barium sulfate, 1-4% by weight calcium carbonate and 0.1-1.0% silica; wherein said additive mixture is dispersed through out the animal chew toy at a concentration to provide a level of barium sulfate at about 0.5-15% by weight in said host polymer material and provides x-ray detection.
