Title:
MICROSPHERE, THERMALLY FOAMABLE RESIN COMPOSITION, FOAM MOLDED BODY AND MANUFACTURING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2017/175519
Kind Code:
A1
Abstract:
Provided are a microsphere exhibiting sharp foaming behavior while maintaining sufficient foaming performance, a thermally foamable resin composition and foam molded body using the same, and a manufacturing method for the foam molded body. The microsphere according to the present invention includes an outer shell including a polymer and a foaming agent enclosed within the outer shell, and satisfies formula (1): 20 ≤ Ts - Tg ≤ 75 (°C). In the formula, Ts (°C) represents the foaming initialization temperature of the microsphere and Tg (°C) represents the glass transition temperature of the polymer.
