Abstract
An elastomeric carboxylated nitirle rubber glove has a stress retention, after six minutes at 100% extension, of rom 50% to 70%. It is made using prevulcanized carboxylated nitrile rubber latex with 2 to 6% by weight methacrylic acid equivalent.
Claims14
An elastomeric glove made of a carboxylated nitrile rubber having from 2 to 6 % by weight methacrylic acid equivalent and which exhibits a stress retention of from 50% to 70%, said stress retention being the percentage retention of the initial stress after six minutes at 100% extension, when wherein prevulcanized rubber latex is used to form the glove.
A method of making a carboxylated nitrile rubber glove having a stress retention of from about 50% to about 70%, said stress retention being the percentage retention of the initial stress after six minutes at 100% extension, which method comprises dipping a former into a pre-vulcanised carboxylated nitrile rubber latex formulation, the rubber having from 2 to 6% methacrylic acid equivalent, the latex formulation containing from 1 to 3 phr sulphur, from 0.5 to 1.5 phr vulcanisation accelerator, and less than 0.5 phr polyvalent metal oxide.
