THERMALLY FOAMING RESIN COMPOSITION, THERMALLY FOAMING RESIN SHEET, FOAM, AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a thermally foaming resin composition and a thermally foaming resin sheet which can be foamed by low-temperature heating, a foam, and a method for manufacturing the same.

SOLUTION: The foam is prepared by foaming by heating at 65°C for 30 min a thermally foaming sheet 1 formed of a thermally foaming resin composition containing: a foaming resin particle which is a solid resin containing a foaming agent and has a bulk density of 15 to 100 g/L after being immersed and foamed in warm water at 70°C; and a resin composition. The foam has a density of 0.05 to 0.75 g/cm3.
