PTFE-free membrane

VAUDE has set itself the goal of becoming Europe’s most sustainable outdoor brand by the year 2015. Many years ago, we decided against the use of PFC and consequently, the use of PTFE-membranes (PFC is needed to make these membranes). Since 2010, VAUDE has only used membranes made from PE or PU. VAUDE makes PTFE-free alternatives with excellent functionality – the Sympatex membrane made from polyetherester (PE) and our in-house Ceplex membrane made from polyurethane. In membranes, VAUDE is therefore 100% PFC-free.


What is actually the problem with PTFE?
Polytetrafluoroethylene (PTFE) is a fluoropolymer, which can be used to manufacture membranes for outdoor products. In recent years it has increasingly come under criticism: The perfluorooctanoic acid (PFOA) required for its production is suspected of being a persistent and bio-accumulative carcinogenic organic substance. This material is not found in nature, but has already been detected as far away as
in Antarctica. Traces of PFOA can also be found in finished products, such as jackets.

In addition, when textiles with PTFE membranes are disposed of, toxic fluoride compounds are released into the environment, typically in the form of hydrofluoric acid and perfluorocarbons.
