RESIN FOAM AND FOAM SEALING MATERIAL

摘要

Provided is a flexible resin foam capable of sufficiently and rapidly recovering from indentation. The resin foam according to the present invention is characterized by having an indentation recovery rate of 50% or more, a repulsive stress of 0.1 to 4.0 N/cm2 at a compression rate of 50%, an average cell diameter of 10 to 200μm, and a maximum cell diameter of 300μm or less. It is preferred that the resin foam has an apparent density of 0.010 to 0.150 g/cm3.
