With the most recent trends in materials and manufacturing techniques, Datwyler is developing an all new approach on how to design and manufacture thin film membranes for various applications within challenging environments. To provide an example, the new membranes feature Polyetheretherketone (PEEK) as a membrane material.
PEEK provides numerous benefits for membranes across the board due to its physical and chemical properties, and offers commercial advantages and an enhanced end-user experience. Datwyler has already implemented and tested a carburetor membrane solution which works in a plug-and-play fashion and shows attractive possibilities regarding feasibility and design.
Datwyler developed a dedicated, new manufacturing technology to process thin, advanced thermoplastic materials, i.e. carburetor membranes in a fast and precise way.
The main issue with rubber-based membranes is swelling. Datwyler has found that swelling of the rubber leads to degradation of the material structure and break down of its mechanical properties and performance. As a result, behavior and function of the membrane are heavily affected. Therefore, using a high-performance polymer instead decreases swelling, while showing prolonged life time and decreased inertia.1
