Abstract

Bellows, for example, a roll bellows and a folding bellows, can be produced that can be used at higher temperatures such as those prevailing in modern articulated constructions, using a mixture comprising at least one thermoplastic elastomer selected from the group of copolysters with a hard segment and a soft segment, wherein in a first step the at least one thermoplastic elastomer is mixed with approximately 0.8 wt. % to approximately 5 wt. % triallyl isocyanurate, based on the total amount of the mixture; in a second step the bellows is produced; and in a third step, the bellows is exposed to an ionizing irradiation in a range from approximately 140 kGy to approximately 350 kGy.
