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 for producing foam particles from expanded thermoplastic elastomer involves (a) mixing a thermoplastic elastomer melt with a blowing agent in an extruder; (b) pressing the thermoplastic elastomer melt mixed with the blowing agent through a die plate into a pelletizing chamber; and (c) comminuting the thermoplastic elastomer melt pressed through the die plate into individual pellets. A liquid flows through the pelletizing chamber, and the pressure and temperature of the liquid are chosen such that the pellets are expanded to a desired degree in the liquid by the blowing agent and solidify to form foam particles. Additionally, the liquid in the pelletizing chamber contains wax which accumulates on the surface of the pellet during the cutting and expansion in the pelletizing chamber; and/or after separation from the liquid and drying of the foam particles, a wax is applied to the foam particles of expanded thermoplastic elastomer.

摘要： A molded body is useful for non-pneumatic tires, in furniture, seating, as cushioning, for car wheels or parts of car wheels, toys, animal toys, as tires or parts of a tire, saddles, balls and sports equipment, for example sports mats, or as floor covering and wall paneling, especially for sports surfaces, track and field surfaces, sports halls, children's playgrounds and pathways. A preparation for the molded body and a process for manufacturing the molded body are also provided.

摘要： A molded body contains foamed pellets, containing a composition (M1) containing a thermoplastic elastomer (TPE-1), having a ratio of average surface area to average volume of the pellets (A/V) determined according to method-example 1 and 2 in a range of from 1.4 to 3.0. A process for preparing the molded body involves providing the foamed pellets comprising the composition (M1), and fusing the foamed pellets to obtain the molded body. A molded body obtained or obtainable by the process is useful in furniture, seating, cushioning, car wheels or parts of car wheels, toys, animal toys, tires or parts of a tire, saddles, balls and sports equipment, sports mats, or as floor covering or wall paneling, especially for sports surfaces, track and field surfaces, sports halls, children's playgrounds, and pathways.

摘要： Laser-markable foamed pellets contain a composition (MI), containing a thermoplastic elastomer (TPE-1) and a color component as component (c1) selected from laser marking additives. A process can be used for producing said laser-markable foamed pellets. The laser-markable foamed pellets according to the present invention can be used for preparing a laser-markable molded body. A process for preparing a laser-markable molded body involves providing and fusing the laser-markable foal led pellets.

摘要： A block copolymer contains at least a block (P1) and a block (P2). The block (P1) is obtained or obtainable by reaction of a triblock copolymer having the structure A-B-A′, where block B is selected from polyethers or polyesters and blocks A and A′ are identical or different, and at least one polymer (PM) selected from polyesters and polyethers. The block (P2) is selected from polyamides and polyesters. A process can be used for producing the inventive block copolymer, a shaped article can be made containing the inventive block copolymer, and the inventive block copolymer can be used for producing a shaped article.
