<P>PROBLEM TO BE SOLVED: To provide a resin foam sheet which has a low apparent density, is thin and flexible, and excels in stability in winding up (wind-up stability). <P>SOLUTION: The resin foam sheet includes an apparent density of 0.03-0.30 g/cm<SP POS="POST">3</SP>, a compression stress at 50% compression of 5.0 N/cm<SP POS="POST">2</SP>or less, a thickness of ≥0.05 and ≤0.40 mm, a length of 5 m or more, a width of 300 mm or more, and in the resin foam sheet, the value obtained from the formula: (tolerance of thickness)/(center value of thickness)×100 is 25% or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
