摘要： A molded body contains foamed pellets, containing a composition (M1) containing a thermoplastic elastomer (TPE-1), having a ratio of average surface area to average volume of the pellets (A/V) determined according to method-example 1 and 2 in a range of from 1.4 to 3.0. A process for preparing the molded body involves providing the foamed pellets comprising the composition (M1), and fusing the foamed pellets to obtain the molded body. A molded body obtained or obtainable by the process is useful in furniture, seating, cushioning, car wheels or parts of car wheels, toys, animal toys, tires or parts of a tire, saddles, balls and sports equipment, sports mats, or as floor covering or wall paneling, especially for sports surfaces, track and field surfaces, sports halls, children's playgrounds, and pathways.

摘要： Expanded poly(lactide) (PLA) beads are made by pressurizing PLA beads with carbon dioxide at approximately room temperature, heating the beads under pressure to 90 to 160 C to saturate and partially crystallize the beads, and then depressurizing and cooling the beads. The PLA beads contain a blend of PLLA and PDLA in certain ratios. The beads are useful for making expanded bead foam.

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 disclosed methods comprise selectively depositing a binding material on foam particles in a target area such that the binding material coats at least a portion of defining surfaces of the foam particles with the binding material. The binding material is then cured to affix foam particles in the target area to one another. In various aspects, the disclosed methods can be used to manufacturer articles with sub-regions that differential levels of affixing between the foam particles, and thereby resulting in sub-regions with different properties such as density, resilience, and/or flexural modulus.
