<p>A rubber composition which comprises: 100 parts by weight of a rubber blend consisting of 99 to 85wt% of chloroprene rubber and 1 to 15wt% of chlorinated polyethylene rubber; either (A) 10 to 30 parts by weight of a polyether ester-type plasticizer having a molecular weight of 450 to 650 or (B) 10 to 30 parts by weight of a mixture of a polyether ester-type plasticizer having a molecular weight of 450 to 900 and an ester-type plasticizer having a molecular weight of 350 to 500; and 3 to 10 parts by weight of multiple aromatic amine antioxidants. The rubber composition simultaneously satisfies the requirements for use as the material of an automobile grease cup or the like, namely, heat resistance, ozone resistance, low-temperature resistance, and adhesion to metal or resin.</p> |
