摘要： A process for producing expanded foam beads from pellets comprising at least one biodegradable polyester. The process comprises (i) producing a suspension comprising pellets in an aqueous suspension medium, (ii) impregnating the pellets present in the suspension from step (i) with at least one physical blowing agent by heating the pellet suspension to a depressurization temperature IMT, with stirring, to provide pellets laden with blowing agent in the suspension medium, and (iii) depressurizing the suspension obtained in step (ii) and cooling the depressurized suspension with a liquid aqueous coolant, in order to obtain the expanded foam beads. The blowing agent can be added in step I, or in step ii during the heating phase or following the heating phase. Following the heating phase, the suspension is maintained at a temperature in the range from IMT minus 5° C. to IMT plus 2° C. for 3 to 100 minutes, and the ratio of aqueous coolant to suspension medium is at least 0.3. The invention further relates to expanded foam beads obtained by the process and to moldings that are produced from the expanded foam beads.

摘要： Molded articles contain a foam composed of a thermoplastic elastotner (TPE-1). The foam has a storage modulus (G modulus) at 25° C. and 1 Hz within the range from 0.01 to 0.5 MPa, a molding density within the range from 20 to 400 kg/m3, and a comfort factor of greater than 4. A process produces molded articles of this kind, and the molded article can be used for producing floors, mattresses, seating furniture, bicycle saddles, car seats, motorcycle seats, components of a shoe, shoe inserts, packaging, shock absorbers, protectors, fall protection mats, elastic insulating material, or sealing material.

摘要： A process can be used for producing a thermoplastic polyurethane, where the process at least involves converting at least one isocyanate composition and a polyol composition, to obtain a prepolymer having isocyanate groups, and reacting the resulting prepolymer with at least one chain extender. The at least one isocyanate composition contains an isocyanate selected from naphthylene 1,5-diisocyanate (NDI), diphenylmethane 4,4′-diisocyanate (MDI), p-phenyl diisocyanate (PPDI), o-tolidine diisocyanate (TODI), ethylene diphenyl diisocyanate (EDI), or mixtures thereof. The polyol composition contains a polytetrahydrofuran or a derivative thereof. A thermoplastic polyurethane obtained or obtainable by such a process is useful, and a foamed pellet material can be produced containing such a thermoplastic polyurethane. The foamed pellet material of the invention can be used for production of a molded article.
