Abstract:
Provided is a shoe sole member partially or entirely formed of a resin composite, the resin composite including; a non-foamed elastic body matrix composed of an elastomer; and a plurality of resin foam particles dispersed in the elastic body matrix. Also provided is a shoe including the shoe sole member.
Abstract:
Provided is a shoe sole member partially or entirely formed of a resin composite in which a plurality of resin foam particles are integrated with one or more non-foamed elastic bodies, wherein a resin composition constituting the one or more elastic bodies and a resin composition constituting the plurality of resin foam particles both include a polyolefin-based resin as a main component, or both include a polyurethane-based resin as a main component. Also provided is a shoe including the shoe sole member.
Abstract:
A laminate of the present invention includes a first member which contains a thermoplastic polymer and through which laser light is transmitted and a second member which contains a thermoplastic polymer and absorbs laser light, wherein the first member is directly bonded to the second member, and A represented by the formula 1: A=−9×D+Wa−45 is more than zero. D represents a distance between a Hansen solubility parameter of the thermoplastic polymer of the first member and a Hansen solubility parameter of the thermoplastic polymer of the second member, and Wa represents work of adhesion calculated from each surface free energy of the first member and the second member. Such a first member and a second member are firmly bonded to each other without using a bonding sheet.
Abstract:
An outsole is formed of a viscoelastic body containing a rubber component. This viscoelastic body has a loss factor measured by a dynamic viscoelasticity measurement under conditions of a temperature of 23° C., a frequency of 10 Hz, a static strain of 10%, and a dynamic strain of 7% being 0.17 or more, a storage elastic modulus measured by the dynamic viscoelasticity measurement being 5.7 MPa or less, and a ratio of a tensile stress at 300% elongation to a tensile stress at 100% elongation being 4.4 or more. Such outsole is excellent in wet grip performance and durability.
Abstract:
Provided is a method for producing a resin molded article including an introducing step of introducing a plurality of resin foam particles and a heat medium substance into a forming mold, and a molding step of, after the introducing step, heating the forming mold to a temperature at which the heat medium substance can be vaporized, thereby obtaining a resin molded article including the plurality of resin foam particles.
Abstract:
Provided in the present invention is a shoe that has a ground engaging surface with a simplified structure and that is excellent in lightweight properties since an outsole is composed of an elastomer sheet including a sheet body and foamed polymer particles dispersed in the sheet body.
Abstract:
There is provided a shoe-forming member comprising a rubber composition containing a styrene-butadiene rubber, a butadiene rubber, silica, a silane coupling agent, and a crosslinking agent, the rubber composition being crosslinked, wherein the rubber composition contains specific materials as the silane coupling agent and the crosslinking agent, and the butadiene rubber and the styrene-butadiene rubber are contained in the rubber composition in predetermined proportions.
