Abstract

The present invention generally relates to vulcanization compositions used to vulcanize elastomeric articles, where the vulcanization compositions have reduced allergenic potential as compared to elastomeric articles formed using vulcanization compositions having non-fugitive accelerators. The present invention also relates to elastomeric articles formed using the vulcanization compositions. The invention further relates to methods for making a reduced-allergenicity vulcanization composition, and to methods for using the vulcanization compositions to vulcanize elastomeric articles.

Claims (32)

1. A vulcanization composition comprising:

a source of sulfur,

a single fugitive xanthate accelerator, and

a metal oxide,

where the composition does not include any additional compounds that function as accelerators for vulcanizing elastomers.

2. The vulcanization composition of claim 1 , wherein the sulfur is elemental sulfur and wherein the single fugitive xanthate accelerator is diisopropyl xanthogen polysulfide.

3. The vulcanization composition of claim 1 , wherein the vulcanization composition exhibits reduced allergenicity as compared to conventional vulcanization compositions.

4. The vulcanization composition of claim 1 , wherein the metal oxide is selected from the group consisting of zinc oxide, magnesium oxide, lead oxide, and combinations thereof.

5. The vulcanization composition of claim 1 , wherein the source of sulfur is selected from the group consisting of elemental sulfur and sulfur donors that have a low allergenic potential, and combinations thereof.

6. The vulcanization composition of claim 1 , wherein the single fugitive xanthate accelerator is selected from the group consisting of diisopropyl xanthogen polysulfide, dibutyl xanthogen disulfide, and diisopropyl xanthogen disulfide.

7. The vulcanization composition of claim 1 , wherein the composition does not contain any additional xanthate compounds.

8. An elastomeric article formed using the vulcanization composition of claim 1 , where the elastomeric article does not include any additional compounds that function as accelerators for vulcanizing elastomers.

9. The elastomeric article of claim 8 , wherein the elastomeric article exhibits reduced allergenicity as compared to elastomeric articles formed using conventional accelerators.

10. The elastomeric article of claim 8 , wherein the elastomeric article is selected from the group consisting of gloves, probe covers, finger cots, catheters, dental dams, and condoms.

11. The elastomeric article of claim 8 , wherein the elastomeric articles are powder free.

12. A vulcanization composition comprising:

a source of sulfur,

a single fugitive xanthate accelerators, and

a metal oxide,

wherein the composition does not include any non-fugitive accelerators; and

wherein the composition does not include any additional xanthate compounds.

13. The vulcanization composition of claim 12 wherein

the source of sulfur is elemental sulfur and

diisopropyl xanthogen polysulfide is the single fugitive xanthate accelerator.

14. The vulcanization composition of claim 12 , wherein the vulcanization composition exhibits reduced allergenicity as compared to conventional vulcanization compositions.

15. The vulcanization composition of claim 12 , wherein the metal oxide is selected from the group consisting of zinc oxide, magnesium oxide, lead oxide, and combinations thereof.

16. The vulcanization composition of claim 12 , wherein the source of sulfur is selected from the group consisting of elemental sulfur and sulfur donors that have a low allergenic potential, and combinations thereof.

17. The vulcanization composition of claim 12 , wherein the single fugitive xanthate accelerator is selected from the group consisting of diisopropyl xanthogen polysulfide, dibutyl xanthogen disulfide, and diisopropyl xanthogen disulfide.

18. An elastomeric article formed using the vulcanization composition of claim 12 , where the elastomeric article does not include any non-fugitive accelerators.

19. The elastomeric article of claim 18 , wherein the elastomeric article exhibits reduced allergenicity as compared to elastomeric articles formed using conventional accelerators.

20. The elastomeric article of claim 18 , wherein the elastomeric article is selected from the group consisting of gloves, probe covers, finger cots, catheters, dental dams, and condoms.

21. The elastomeric article of claim 18 , wherein the elastomeric articles are powder free.
