    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.
