Thermoplastic elastomers
Thermoplastic elastomers made of 48 to 88% by weight of ethylene-propylene-diene-rubber (EPDM), 10 to 50% by weight of polypropylene (PP) and 2 to 20% by weight of a third polymer and 5 to 60% by weight of softening oil, based on the total of EPDM, PP and the third polymer, and optionally further co...

| Zusammenfassung: | Thermoplastic elastomers made of 48 to 88% by weight of ethylene-propylene-diene-rubber (EPDM), 10 to 50% by weight of polypropylene (PP) and 2 to 20% by weight of a third polymer and 5 to 60% by weight of softening oil, based on the total of EPDM, PP and the third polymer, and optionally further conventional constituents, have the advantage that the softening oil does not exude.
PROCEDIMIENTO PARA LA OBTENCION DE ELASTOMEROS TERMOPLASTICOS, CARACTERIZADO PORQUE A LA MEZCLA DE UN 48 HASTA 88% EN PESO DE CAUCHO DE ETILENO-PROPILENO-DIENO (EPDM), UN 10 HASTA UN 50% EN PESO DE POLIPROPILENO (PP) SE LE AGREGA UN 2 HASTA UN 20% DE UN TERCER POLIMERO, DE MANERA QUE CONTENGA UN 5 HASTA UN 60% EN PESO DE ACEITE PLASTIFICANTE, REFERIDO A LA SUMA DE EPDM, PP Y EL TERCER POLIMERO, Y EN CASO DADO ULTERIORES COMPONENTES USUALES. |
