GLASS BUBBLE, MASTER BATCH INCLUDING THE SAME, AND RESIN PARTICLE HAVING METAL FILM FORMED ON SURFACE

摘要

PROBLEM TO BE SOLVED: To provide a surface-treated glass bubble capable of embodying metal texture, having a specific gravity similar to plastic, and having a low occurrence rate of an appearance failure even when being compounded with plastic and injected; and to provide a master batch including a glass bubble and plastic so that kneadability between the glass bubble and the plastic can be improved.SOLUTION: A glass bubble includes a spherical shell (Shell) and a surface-treated layer formed on a shell surface; wherein the spherical shell has a hollow inside so that its specific gravity is reduced, and the surface-treated layer is formed by surface treatment for embodying metal texture.
