PFAS-free · PTFE replacement

UHMWPE liner

A PFAS-free liner that replaces PTFE liner. In the same size range it has better wear resistance than etched PTFE liner. Since 2025 we have been co-developing a UHMWPE+TPU material for long-term implants with DSM.

FAQ

FAQ

Can UHMWPE replace a PTFE liner?

Yes. We supply UHMWPE liner in the same size range, with better wear resistance than etched PTFE liner. The published sample spec is ID 3.41 mm × wall 0.03 mm.

Is UHMWPE liner PFAS-free?

Yes. UHMWPE contains no fluorine and is not subject to PFAS regulation. It is used when evaluating alternatives to PTFE, FEP, PFA and other fluoropolymers.

Does it work in reinforced builds?

Yes. A UHMWPE + SS304 + TPU build replaces the conventional PTFE + SS304 + TPU structure.

Can I get a sample?

Yes. Tell us the dimensions and application you need and we reply with sample terms.

Is there quantitative data against PTFE?

The published material states only the wear-resistance advantage and PFAS-free status. Numerical comparisons such as friction coefficient are requested from the plant and reported back.

Can I get the TDS and MSDS?

Yes. We send the TDS and MSDS with every specification reply. Biocompatibility test data is confirmed with the factory on request.
