Description

Polytetraflon® PTFE Bellows - Customized Design and Performance

PTFE bellows are used, for example, as compensating elements between engineered parts. By specifically using different fold geometries, any combination of properties can be achieved as required—for example, high flexibility or compressive strength.


The outstanding material properties of PTFE allow bellows to be used increasingly in the medical and food sectors, as well as in general industry.
