The foaming Characteristic synthetic resin constituent, production manner null of the synthetic resin foaming body and the synthetic resin foaming

摘要

An expandable synthetic resin composition capable of providing a synthetic resin foam excellent in both heat distortion resistance and mechanical strength, as well as such a synthetic resin foam, are provided. An expandable synthetic resin composition incorporating a thermoplastic resin, a liquid crystal resin and a heat-decomposable foaming agent, as well as a synthetic resin foam which incorporates a thermoplastic resin and a liquid crystal resin dispersed in the thermoplastic resin and exhibits an expansion ratio of 1.1 - 50, are provided.
