PROBLEM TO BE SOLVED: To provide: a heat-shrinkable tubing having excellent dimensional stability and wear resistance while maintaining conventional satisfactory mechanical characteristics and processability; and a rubber composition.SOLUTION: A heat-shrinkable tubing and a rubber composition respectively contain ethylene propylene rubber, polyethylene whose crystallinity is 90% or more, and an oil. Not less than 65 pts.wt. nor more than 95 pts.wt. of the polyethylene, and not less than 100 pts.wt. nor more than 140 pts.wt. of the oil are blended to 100 pts.wt. of the ethylene propylene rubber. |
