摘要：
In order to provide a rubber composition having high transparency, toughness and heat-resisting property, the present invention can provide a composition comprising a neodymium-catalyzed isoprene rubber (IR) component; and a rubber polymer (RB) component selected from the group consisting of BR, 1,2-polybutadiene rubber, and SBR, wherein the amount of IR is from about 5 to 95 mass parts with the proviso that the total amount of IR and RB is 100 mass parts, wherein the composition is substantially free of silica, wherein the composition has haze of less than about 20%, and wherein the composition has Type A Durometer hardness (0 sec) of about 30 or more.
