Abstract

A latex article is provided that contains chromium oxide particles dispersed throughout a cured latex layer. The chromium oxide particles render the latex article, or smaller pieces of the latex article, magnetically detectable. The chromium oxide may be present within the latex in combination with magnetically detectable ferrite. The article may include multiple cured latex layers having chromium oxide or magnetically detectable ferrite dispersed throughout the cured latex layers.

Claims (29)

1. A magnetically detectable latex article, comprising:

a glove having a cured latex layer; and

chromium oxide dispersed throughout the cured latex layer.

2. The latex article of claim 1 , wherein the cured latex layer comprises a latex selected from the group consisting of nitrile, natural rubber, polyurethane, and polychloroprene latex.

3. The latex article of claim 1 , wherein the chromium oxide is present in the cured latex layer in an amount that is from about 1 to about 50 parts per hundred parts of the total weight of the cured latex layer.

4. The latex article of claim 1 , wherein the chromium oxide is Cr 2 O 3 .

5. The latex article of claim 1 , wherein the chromium oxide is CrO 2 .

6. The latex of claim 1 , wherein the chromium oxide is a mixture of Cr 2 O 3 and CrO 2 .

7. A magnetically detectable latex article, comprising:

a glove having a cured latex layer; and

chromium oxide dispersed throughout the cured latex layer; and

ferrite dispersed throughout the cured latex layer.

8. The latex article of claim 7 , wherein the cured latex layer comprises a latex selected from the group consisting of nitrile, natural rubber, polyurethane, and polychloroprene latex.

9. The latex article of claim 7 , wherein the chromium oxide and ferrite are present in the cured latex layer in a total amount that is about 1 part per hundred parts to about 50 parts per hundred parts of the total weight of the cured latex layer.

10. The latex article of claim 7 , wherein the chromium oxide is Cr 2 O 3 .

11. The latex article of claim 7 , wherein the chromium oxide is CrO 2 .

12. The latex article of claim 7 , wherein the chromium oxide is a mixture of Cr 2 O 3 and CrO 2 .

13. The latex article of claim 7 , wherein the ferrite is magnetite.

14. A magnetically detectable latex article, comprising:

an outer cured latex layer, the outer cured latex layer comprising chromium oxide dispersed throughout the outer cured latex layer;

a middle cured latex layer, the middle cured latex layer comprising ferrite dispersed throughout the middle cured latex layer; and

an inner cured latex layer, the inner cured latex layer comprising chromium oxide dispersed throughout the inner cured latex layer.

15. The latex article of claim 14 , wherein the cured latex layers comprise a latex selected from the group consisting of nitrile, natural rubber, polyurethane, and polychloroprene latex.

16. The latex article of claim 14 , wherein the chromium oxide is present in the outer cured latex layer in an amount that is from about 1 to about 50 parts per hundred parts of the total weight of the outer cured latex layer.

17. The latex article of claim 14 , wherein the chromium oxide is Cr 2 O 3 .

18. The latex article of claim 14 , wherein the chromium oxide is CrO 2 .

19. The latex article of claim 14 , wherein the chromium oxide is a mixture of Cr 2 O 3 and CrO 2 .

20. The latex article of claim 14 , wherein the ferrite is magnetite.

21. The latex article of claim 14 , wherein the latex article is a glove.
