Abstract

PURPOSE: To provide a rubber composition with low migration of a softening agent within vulcanized products and excellent processability obtained by compounding a petroleum-based binder to a rubber-like elastomer.
CONSTITUTION: To 100pts.wt. of a rubber-like elastomer, is compounded as softening agent 5W50pts.wt., pref. 10W30pts. of a petroleum-based binder obtained by heat treating an extract with b. p. of 300W600°C extracted from a petroleum stock by furfural or phenol or the like at 260W500°C for 5W15hr. The obtained rubber composition has good processability as well as remarkably low migration of the softening agent from vulcanized products thereof. When this composition is used as part of a composite material product such as tire or the like, improper adhesion with other vulcanized rubber to be contacted and lowering of vulcanization characteristic due to migration of softening agent can be prevented.
