Abstract
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.
Claims (21)
1. An animal chew toy comprising a radiopaque polymer material.
2. The animal chew toy of claim 1, wherein said polymer is a thermoplastic elastomer.
3. The animal chew toy of claim 1 wherein said polymer is a polyurethane.
4. The animal chew toy of claim 1 wherein said polymer is a polyamide.
5. The animal chew toy of claim 1 wherein said polymer is starch.
6. An animal chew toy comprising a host polymer material and a radiopaque additive.
7. The animal chew toy of claim 6 wherein the radiopaque additive comprises barium sulfate.
8. The animal chew toy of claim 6 wherein the radiopaque additive comprises a mixture of barium sulfate, calcium carbonate and silica.
9. The animal chew toy of claim 8 wherein said mixture comprises 97-99% by weight barium sulfate, 1-4% by weight calcium carbonate and 0.1 -1.0% silica.
10. The animal chew toy of claim 9 wherein the barium sulfate is present at a level of about 1-15% by weight.
11. A method for incorporating a radiopaque additive into a polymer material and shaping such polymer material into an animal chew toy comprising:
a. providing a polymer resin;
b. providing a radiopaque additive;
c. melt compounding said radiopaque additive into said polymer resin, to a first desired level of concentration of said additive in said polymer;
d. recovering the product of step (c) and mixing said product with additional amounts of said polymer resin to provide a second level of desired concentration of said additive in said polymer, wherein said second level is lower than said first level;
e. molding the product of step (d) in the form of an animal chew.
a. providing a polymer resin;
b. providing a radiopaque additive;
c. melt compounding said radiopaque additive into said polymer resin, to a first desired level of concentration of said additive in said polymer;
d. recovering the product of step (c) and mixing said product with additional amounts of said polymer resin to provide a second level of desired concentration of said additive in said polymer, wherein said second level is lower than said first level;
e. molding the product of step (d) in the form of an animal chew.
12. The method of claim 11 wherein said polymer resin is a thermoplastic elastomer.
13. The method of claim 11 wherein said thermoplastic elastomer is a polyurethane.
14. The method of claim 11 wherein said first desired level of concentration of said additive comprises 20 - 85% by weight.
15. The method of claim 11 wherein said second level of desired concentration of said additive comprises 0.5 -15% by weight.
16. The method of claim 11 wherein said radiopaque additive comprises a mixture of barium sulfate, calcium carbonate and silica.
17. The method of claim 16 wherein said mixture comprises 97 - 99% by weight barium sulfate, 1 - 4% by weight calcium carbonate and 0.1-1.0% by weight silica.
18. An animal chew toy comprising polyurethane and barium sulfate at a level of about 0.5 -15% by weight.
19. The animal chew toy of claim 18 wherein said barium sulfate level is 1.0 -10.0% by weight.
20. The animal chew toy of claim 18 wherein said barium sulfate level is about 5.0% by weight.
21. The animal chew toy of claim 18 wherein said barium sulfate is provided from a mixture of barium sulfate, calcium carbonate and silica.
