Resin Foam and Foam Sealing Material

摘要

There is provided a resin foam excellent in dustproofness and assemblability. The resin foam has a repulsive stress at 80% compression (repulsive stress when a resin foam is compressed by 80% of the initial thickness) of 1.0 to 9.0 N/cm 2 and a tensile modulus of elasticity of 5.0 to 14.0 MPa. Preferably, the resin foam further has an average cell diameter of 10 to 180 µm and an apparent density of 0.01 to 0.10 g/cm 3 .
