Patent ID: 7730554

Claim:
A glove, comprising: a first layer formed from a first composition comprising a first nitrile butadiene rubber; and a second layer formed from a second composition comprising a second nitrile butadiene rubber; wherein the glove exhibits a stress retention of greater than 50%, said stress retention being the percentage retention of the initial stress after six minutes at 100% extension of the glove, the first nitrile butadiene rubber composition comprises a first amount of a metal oxide ionic cross-linking agent, the second nitrile butadiene rubber composition comprises a second amount of the metal oxide ionic cross-linking agent, the first amount of the metal oxide ionic cross-linking agent present in the first nitrile butadiene rubber composition is less than the second amount of the metal oxide ionic cross-linking agent present in the second nitrile butadiene rubber composition, the first nitrile butadiene rubber composition further comprises a first amount of a covalent cross-linking agent, the second nitrile butadiene rubber composition further comprises a second amount of the covalent cross-linking agent, the first amount of the covalent cross-linking agent present in the first nitrile butadiene rubber composition is less than the second amount of the covalent cross-linking agent present in the second nitrile butadiene rubber composition, and the glove has a tensile strength of from about 15 MPa to about 25 MPa and an ultimate elongation of from about 550% to about 650%.
