摘要：
Provided are a vulcanizate of a chloroprene rubber composition containing carbon black that generates a smaller amount of heat when used and a method for producing the same by a simpler and more convenient method. First, an unvulcanized rubber composition at least containing a chloroprene polymer and carbon black is vulcanization-molded, to give a semivulcanized molded article having a cure characteristic value, as determined by the method specified in JIS K6300-2: 2001, in the range of t10 to t80. Then, the semivulcanized molded article obtained by semivulcanized film-forming step is additionally vulcanized in the state as it is deformed entirely and the deformation is removed, to give vulcanizate in a desired shape.
