Polyamide-based resin expanded beads contain a polyamide-based resin as a base material resin. The beads have a crystal structure, an intrinsic peak of the polyamide-based resin and a high-temperature peak having a peak top temperature on a higher temperature side than a peak top temperature of the intrinsic peak appear in a DSC curve obtained under a predetermined condition; an amount of heat of fusion of the high-temperature peak is within 5 J/g or more and 50 J/g or less; and a coefficient of variation of the amount of heat of fusion of the high-temperature peak is 20% or less. The beads are produced by in-mold molding. A method for producing the beads includes: impregnating a polyamide-based resin; and releasing expandable polyamide-based resin beads from a sealed container, a temperature in the sealed container is raised at a rate of 0.3° C. or higher and 1.5° C. or lower per 10 minutes.

High-temperature foams are produced and used in the construction of aeroplanes, ships and rail and other vehicles. In particular, the foams are further processed into sandwich materials by joining with two outer layers. To this end, a novel process is used for producing high-temperature foams (HT foams) which are particularly suitable for producing such sandwich components for lightweight construction. This process achieves an improvement in the processability of the HT foams produced and a weight reduction of the sandwich materials. The HT foams are furthermore rigid particle foams which are markedly more economic to produce than rigid block foams. In particular, a reduction is brought about in resin absorption in fibre composite processes through a process-related optimization of the surface constitution.

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.
