Abstract

This invention concerns a process for producing particle foam part in which foam particles are heated in a molding tool so that they weld to the particle foam part. Heat is supplied to the foam particles by means of electromagnetic RF radiation. The foam particles are made of polyurethane (PU), polylactate (PLA), polyethylene block amide (PEBA) or polyethylene terephthalate (PET).
