PROBLEM TO BE SOLVED: To provide an expanded sheet that exhibits a moderate tackiness, a good wet skid resistance, an abrasion resistance and an impact resistance, as well as to provide a method for producing an expanded sheet that can improve the workability.SOLUTION: Provided is: an expanded sheet obtained by forming a raw-material containing (A) a hydrogenated butadiene-based polymer having a number average molecular weight of 2,000 to 3,500, (B) a thermoplastic polymer other than (A) component, and (C) a blowing agent, into sheet-shape, and in which the hydrogenated butadiene-based polymer (A) is heated to 180°C to 200°C and mixed into the raw-material; and an expanded sheet in which the hydrogenated butadiene-based polymer (A) contains 1,2-vinyl bond by 50% or more, both ends comprises a hydroxyl group, and the incorporation amount is 2 to 10 weight% relative to the raw-material total amount.SELECTED DRAWING: Figure 1 |
