MEMBER FOR SHOE SOLES, AND SHOE

Document Type and Number:

WIPO Patent Application WO/2017/094131

Kind Code:

A1

Abstract:

Provided is a member for shoe soles which has a part or the entirety thereof formed of a resin foam obtained by integrating a plurality of foamed resin particles, the foamed resin particles being each formed of a resin composition including a polyamide-based elastomer, wherein, in dynamic viscoelasticity measurement, when the loss factor of the resin foam at -20ºC is defined as tanδ[-20ºC], when the loss factor of the resin foam at 25ºC is defined as tanδ[25ºC], when the storage elastic modulus of the resin composition at 25ºC is defined as E'[25ºC], and when the minimum value and the maximum value of the complex viscosity of the resin composition at 100-130ºC are respectively defined as ηmin and ηmax, the resin foam satisfies all of (1)-(4): 1≤tanδ[-20ºC]/tanδ[25ºC]≤5···(1), 50MPa≤E'[25ºC]≤400MPa···(2), 0.05MPa·s≤ηmin···(3), and ηmax≤0.6MPa·s···(4).
