Abstract:
A thin walled rubber latex material, comprising:a thin base layer formed of a substantially sulfur free and substantially nitrosamine free rubber latex composition, said rubber latex composition being formed from a prevulcanization mixture comprising a natural rubber latex, an oxygen-donating curing agent, an activating agent, and at least one of an emulsifier and a stabilizer therein; wherein the prevulcanization mixture is vulcanized into a cured latex emulsion, prior to its being formed into the base layer, and wherein vulcanization of the prevulcanization mixture is permitted to go substantially to completion, such that substantially none of the oxygen-donating curing agent from the prevulcanization mixture remains free in the base layer; and a coating provided over the base layer for blocking transfer of latex proteins therefrom, the coating being heat-resistant and water-resistant such that it remains in a substantially non-flowable state after prolonged contact with a human body, and comprises a silicone based coating, or a first layer of a first wax and a second layer of a second wax disposed over said first layer, said second wax having a higher melting point than said first wax.
