Elastomer rubber and elastomer product that do not use vulcanization accelerator or sulfur
An elastomer composition comprising, an emulsion which comprises 25-30 weight % of acrylonitrile, 62-71 weight % of butadiene and 4-8 weight % of unsaturated carboxylic acid (total 100 weight %), wherein crosslink is formed by a bond through at least a part of substituent which is possessed by said unsaturated carboxylic acid, and residual substituent of at least one part of substituent which is possessed by said unsaturated carboxylic acid is left in state of free, further Mooney viscosity (ML(1+4)(100° C.)) of the crosslinked product is 100-220, wherein thin film gloves composed of said elastomer does not contain sulfur which is a crosslinking agent and sulfur composition which is a vulcanization accelerator, thickness is 0.05-0.15 mm, gloves swelling ratio at gloves formation is 240-320, tensile stress is 22-35 MPa, elongation to break is 480-620% and tensile stress at 500% elongation is 15-35 MPa.
