Title:
METHOD FOR PRODUCING A BELLOWS
Document Type and Number:
WIPO Patent Application WO/2019/137753
Kind Code:
A1
Abstract:
To solve the problem of providing a method for producing a bellows, more particularly a roll bellows and a folding bellows, by means of which method bellows can be produced that can be used at higher temperatures such as those prevailing in modern articulated constructions, the invention proposes a method of this kind 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 ionising irradiation in a range from approximately 140 kGy to approximately 350 kGy.
