摘要： Foamed articles including a foamed thermoplastic elastomeric material, methods of making the foamed articles, and methods for manufacturing articles of footwear, apparel, and athletic equipment incorporating such foamed articles are provided. In one aspect, a method for making a foamed article comprises placing an article comprising a foamable material and carbon dioxide in a vessel, maintaining the vessel at a first pressure and first temperature at which the carbon dioxide is a liquid and carbon dioxide is soluble in the foamable material, optionally exposing the infused article to a second temperature and second pressure, and subjecting the article to a third pressure and third temperature at which the infused carbon dioxide phase transitions to a gas, thereby expanding the foamable material into a foamed material and forming the foamed article.

摘要： Methods for manufacturing articles of footwear are provided. In various aspects, the methods comprise utilizing additive manufacturing methods with foam particles. In some aspects, the additive manufacturing methods comprise increasing the temperature of a plurality of foam particles with actinic radiation under conditions effective to fuse a portion of the plurality of foam particles comprising one or more thermoplastic elastomers. Increasing the temperature of the foam particles can be carried out for one or multiple iterations. The disclosed methods can be used to manufacturer articles with sub-regions that exhibit differing degrees of fusion between the foam particles, thereby resulting in sub-regions with different properties such as density, resilience, and/or flexural modulus. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

摘要： Disclosed are a supercritical thermoplastic foam elastomer material and a preparation method and application thereof, belonging to the technical field of foam materials. The supercritical thermoplastic foam elastomer material comprises a thermoplastic elastomer, talc powder, a chain extender and an auxiliary material. According to the invention, a TPU raw material is injection-molded into a shape corresponding to a midsole, and can be directly molded after foaming without being cut. In addition, because the TPU raw material is integrally formed by injection molding, the particles of the popcorn material will not be adhered, and the defect of adhesion between the particles can be ameliorated.
