Abstract: A process for producing a molded article involves providing a thin-walled, gas-permeable shell; filling the shell with a foamed pelletized material composed of a polymer; and welding the foamed pelletized material to obtain the molded article. Molded articles are obtainable or obtained by such a process, and can be used as a footwear sole, part of a footwear sole, a mattress, a seat cushion, an underlay, a grip, a protective film, a component in automobile interiors and exteriors, a gymnastics mat, a body protector, a trim element in automobile construction, a sound insulator, a vibration damper, a cushion, a bicycle saddle, a toy, a tire or part of a tire, a covering for a track and field surface, a covering for a sports hall or a pathway, a damping layer or a damping core in a sandwich element, or a packaging.

Abstract: A composite material contains a nonwoven layer (i) which contains fibers formed from a first thermoplastic elastomer having meshes with a mesh size in the range from 10 to 100 μm, and a membrane layer (ii) which contains a second thermoplastic elastomer and having a layer thickness of less than 30 μm. The membrane is either pore-free (ii.1) or is porous and has pores with an average pore diameter of less than 2000 nm (ii.2). The membrane (ii) is at least partially in direct contact with the fibers of the nonwoven layer (i) and covers the mesh openings in the nonwoven layer (i) at least partially. The fibers of the first nonwoven layer (i) and the membrane (ii) in the contact area are at least partly joined to one another in an interlocking manner.
