Abstract
Disclosed is a rubber composition containing 100 parts by weight of a rubber blend comprising 99-85 by weight % of chloroprene rubber and 1-15 by weight % of chlorinated polyethylene rubber, (A) 10 to 30 parts by weight of a polyether ester-based plasticizer having a molecular weight of 450 to 650, or (B) 10 to 30 parts by weight of both of a polyether ester-based plasticizer having a molecular weight of 450 to 900 and an ester-based plasticizer having a molecular weight 350 to 500, and 3 to 10 parts by weight of two or more aromatic amine-based antioxidants. The rubber composition can simultaneously satisfy requirements for use as, for example, an automobile grease cup material, that is, heat resistance, ozone resistance, cold resistance, and adhesion to metal or resin.
