Title:

HOLLOW PARTICLE AND METHOD FOR PRODUCING SAME, AND RESIN COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2022/145350

Kind Code:

A1

Abstract:

The present invention pertains to hollow particles each having a cavity inside a non-porous outer shell. The hollow particles have a mean particle diameter (D50) of 0.1-10 μm, and, when being suspended in water, the proportions of floating particles, suspended particles, and sedimented particles are 0.5-7.0 mass%, 0-4.0 mass%, and 89.0-99.5 mass%, respectively. An insulation material having such hollow particles blended therein is capable of having a low dielectric constant and a low dielectric loss tangent.
