ABSTRACT:
A rubber composition capable of giving a non-tacky vulcanized rubber can be obtained by mixing 98 to 80% by weight of at least one organic rubber selected from natural rubber and organic synthetic rubbers and 2 to 20% by weight of a silicone raw rubber having a molecular weight of 100,000 to 1,000,000. A conveyor belt in which at least the surface layer is composed of a vulcanizate of this rubber composition is suitable for carrying highly tacky substances such as oil sand.
