Abstract

PURPOSE: To provide a rubber composition having high hardness and high modulus, and useful for tire and industrial product having low heat-generating chracteristics, especially excellent blow-out resistance, by adding sulfur to a mixture of 1,2-polybutadiene and a rubber.
CONSTITUTION: The title tubber composition composed of (A) 10W50 parts by weight of a 1,2-polybutadiene having a vinyl content of ≥70%, crystallinity of 5W40%, and intrinsic viscosity of ≥0.7 (in toluene at 30°C), (B) 90W50 parts by weight of natural rubber, polyisoprene rubber, styrene-butadiene copolymer rubber and/or polybutadiene rubber, and (C) 3W10 parts by weight of sulfur.
