PROBLEM TO BE SOLVED: To obtain a chloroprene rubber composition which gives a vulcanized chloroprene rubber which gives excellent expansion upon cutting, and has excellent tensile strength, and a low impact embrittlement temperature. SOLUTION: This composition is obtained by mixing (A) 100 pts.wt. of chloroprene rubber, (B) 1-15 pt(s).wt. of a condensate from an alkylnaphthalene having an alkyl group of a carbon number of 2 or more and formaldehyde, (C) 20-40 pts.wt. of carbon black, and (D) at least one agent(s) selected from a group comprising vulcanizing agent, vulcanization-enhancing agent, vulcanization enhancement auxiliary, antioxidant, plasticizer, softener, lubricant, and filler, the total weight of A, B, C, and D being 140170 pts.wt. |
