An object of the present disclosure is to provide a rubber composition from which a crosslinked rubber molded product having good softness and excellent resilience performance can be obtained. The present disclosure provides a rubber composition containing (a) a base rubber, (b) a co-crosslinking agent, (c) a crosslinking initiator, and (d) a salt of a benzothiazole derivative, wherein (d) the salt of the benzothiazole derivative includes a compound represented by the formula (1) in which a sulfur atom S2 constituting a thiocarbonyl group has a Mulliken charge of −0.190 or more. [In the formula (1), R1 to R4 are identical to or different from each other, and represent an electron-withdrawing group or a hydrogen atom, S1 and S2 represent a sulfur atom, X represents a cation component, n is an integer ranging from 1 to 4, and at least one of R1 to R4 bonding to the identical benzene ring is an electron-withdrawing group when n is 2 or more.]
A rubber composition containing (a) a base rubber, (b) a co-crosslinking agent, (c) a crosslinking initiator, and (d) a salt of a benzothiazole derivative,
A crosslinked rubber molded product formed from a rubber composition containing (a) a base rubber, (b) a co-crosslinking agent, (c) a crosslinking initiator, and (d) a salt of a benzothiazole derivative,
