THERMOPLASTIC RESIN FOAM, PROCESS FOR PRODUCING THERMOPLASTIC RESIN FOAM, AND LIGHT REFLECTION MATERIAL

摘要

A thermoplastic resin foam, having a bubble with an average bubble diameter of 10 µm or less in the inside thereof, in which wherein the thermoplastic resin foam is prepared by using and foaming a thermoplastic resin composition containing 0.25 to 2.5 part(s) by mass of a melt-type crystallization nucleating agent (B), with respect to 100 parts by mass of an amorphous thermoplastic resin (A).
