A shoe member consisting of a material comprising a thermoplastic elastomer, wherein the material has a glass transition temperature Tg of no more than 10° C., a loss tangent tan δ of no less than 0.4 in a test of dynamic viscoelasticity, and a Δ tan δ, which is the amount of change of tan δ, of no less than 0.15 when strain is changed from 5% to 100%.

A thermoplastic polyurethane (TPU) foam product with high flatness, and a preparation method and a use thereof are provided. The TPU foam product is prepared by processing aliphatic thermoplastic polyurethane (ATPU) beads with a melting range of 20° C. to 50° C. and a melting point of 90° C. to 160° C. by a physical gas foaming process to obtain foamed ATPU beads and heating the foamed ATPU beads with a heat source to make the foamed ATPU beads fused. The TPU foam product with high flatness has a density of 0.08 g/cm.sup.3 to 0.8 g/cm.sup.3 and a flatness value of less than 2 mm, and the flatness value is determined by a fixed-length ruler. The TPU foam product not only has high flatness such that diversified designs are allowed for a surface of the product, but also has high resilience.

Improved soles and insoles for shoes, in particular sports shoes, are described. In an aspect, a sole for a shoe, in particular a sports shoe, with at least a first and a second surface region is provided. The first surface region comprises expanded thermoplastic polyurethane (“TPU”). The second surface region is free from expanded TPU.

This document discloses algae-derived flexible foams, whether open-cell or closed-cell, with inherent antimicrobial and flame resistant properties, wherein a process of manufacturing includes the steps of: harvesting algae-biomass; sufficiently drying the algae biomass; blending the dried algae biomass with a carrier resin and various foaming ingredients; adding an algal-derived antimicrobial compound selected from various natural sulfated polysaccharides present in brown algae, red algae, and/or certain seaweeds (marine microalgae); and adding a sufficient quantity of dried algae biomass to the formulation to adequately create a fire resistant flexible foam material.

Described herein is a 3D spacer fabric reinforced composite, a process for producing it, a method of using it in footwear, and a footwear including it.

The present invention relates to gel compositions comprising a polyurethane elastomer. The polyurethane elastomer is formed from the reaction of a polyol, a polyisocyanate, and optionally a polyurethane reaction catalyst, optionally in the presence of a topically acceptable carrier fluid. In some embodiments, the gel composition comprises a personal active ingredient or a healthcare active ingredient, which may be incorporated into the gel composition via a pre-load method or a post-load method. Also provided herein are gel pastes and topical formulations comprising the polyurethane elastomers, and methods of making the same.

A molded article (M) contains a molded article (M-1) made of a thermoplastic elastomer (TPE-1) and a foamed pellet material made of a thermoplastic elastomer (TPE-2). The molded article (M-1) has a softening temperature TS (TPE-1) that deviates by no more than 25° C. from the processing temperature TP (TPE-2) of the thermoplastic elastomer (TPE-2). The softening temperature is determined by TMA in accordance with ISO 11359-3:2014. A process can be used for producing the molded article. The molded article can be used for application in the sports, industry, medicine, sports medicine, safety, automotive and consumer goods field, especially as a shoe sole, a part of a shoe sole, a bicycle saddle, a cushioning, a mattress, an underlay, a grip, a protective film, or a component in automobile interiors and exteriors.

A foamable polyurethane resin composition includes a polyisocyanate material, a polyol material, water, and a catalyst. The polyisocyanate material contains 1,4-H.sub.6XDI; the polyol material contains crystalline PTMEG and noncrystalline PTMEG and/or PPG; the total amount of the crystalline PTMEG, the noncrystalline PTMEG, and PPG is 90% by mass or more with respect to the total amount of the polyol material; and a ratio of the crystalline PTMEG is 60% by mass or more and 90% by mass or less with respect to the total amount of the crystalline PTMEG, the noncrystalline PTMEG, and PPG.

The invention concerns cushioning compositions comprising (a) at least one of urethane polymer and silicone polymeric putty; and (b) hydraulic silicone crumb; said hydraulic silicone crumb being mixed with component (a). The invention also concerns devices and methods using such compositions. Protective devices have been used to protect the hoofs of animals. Shoes have been used to protect the hoofs from damage while the animal is walking or running.
