FOAM COMPOSITION FOR FILLING/SEALING PURPOSES, FOAM MEMBER FOR FILLING/SEALING PURPOSES, AND FOAM BODY FOR FILLING/SEALING PURPOSES

摘要

A foam composition for filling/sealing purposes comprises a vinyl copolymer having an ester bond in a side chain, an organic peroxide, a foaming agent, a hydrophobic resin, and a hydrophilic resin. The content ratio of the hydrophobic resin is 5-25 parts by mass relative to 100 parts by mass of the vinyl copolymer. The content ratio of the hydrophilic resin is 1-20 parts by mass relative to 100 parts by mass of the vinyl copolymer.
