摘要： 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.]

摘要： The present invention relates to an anti-tack formulation of high solids content that uses effective amounts of a fine particle size talc, a water soluble cationic polymer, one or more nonionic surfactants, and one or more alkali metal fatty acid soaps. The high solids content anti-tack formulation is capable of being easily shipped to a customer's location and is stable and easily pumped after shipment to a customer. The high solids content anti-tack formulation can be diluted to a low solids content formulation for use in anti-tack applications, particularly rubber slab dipping applications. The anti-tack formulation provides improved anti-tack performance when coating uncured rubber products.

摘要： Provided are a rubber composition for tires having low tan δ at approximately 60° C. and excellent breaking energy at approximately 25° C.; a method for preparing the rubber composition for tires; and a tire thereof. The present invention relates to a rubber composition for tires which contains a rubber component including an isoprene-based rubber, and which has a correlation length Ξb of 50 nm or less as determined by fitting the following Equations 1 to 6 to a scattering intensity curve I(q) obtained by X-ray scattering analysis or neutron scattering analysis: I ( q ) = A 1 + q 2 ξ 2 + B ( 1 + q 2 Ξ b 2 ) 2 + C ( 1 + q 2 Ξ c 2 ) 2 ( Equation 1 ) ξ
