Compositions for foam molding, foamed bodies, and components

Abstract

This invention provides a composition for foam molding, which exhibits excellent foaming properties and results in a foamed molded body (foamed body) with excellent strength, thermal expansion during combustion, and shape stability after combustion. According to this invention, a composition for foam molding is provided, comprising a crosslinkable rubber component, a phosphoric acid-based inorganic compound, a crosslinking agent, and a foaming agent. Relative to 100 parts by mass of the crosslinkable rubber component, the content of the phosphoric acid-based inorganic compound is 10 to 2000 parts by mass, the content of the crosslinking agent is 0.1 to 30 parts by mass, the content of the foaming agent is 1 to 30 parts by mass, and the content of the thermally expanding layered inorganic compound is less than 5 parts by mass.
