PFAS-free technical parts

Given the environmental controversies surrounding fluoropolymers, ultra-high molecular weight polyethylene is increasingly popular for the manufacture of bellows. Indeed, PE-1000 exhibits exceptional resistance to repeated flexing and is physiologically harmless. Furthermore, it complies with FDA, 3A, and EC 10/2011 standards.

Rounded pleats will be preferred for applications requiring good bellows cleanability. When the bellows stroke is very large, the machining of pointed pleats is recommended.

Unlike PTFE bellows commonly reinforced with PTFE bases or PEEK in stressed areas (threads, guide surfaces, etc.), PFAS-free bellows do not require reinforcement as they can be made from highly resistant materials in a single piece: Enduflon P1 and P16.

For use in potentially explosive atmospheres, a bellows can be made electrically conductive using a conductive pigment. This component made of Enduflon P10 – which is black due to carbon – is ATEX-compliant. Its resistance to repeated flexing is reduced as a result, but remains sufficient for most applications.

We support you at all stages of your bellows' development: from the initial sketch to construction, from sampling with multiple variations to mass production. Bench testing is also possible. Let us know your requirements!
