We also support you in geometry design and the choice of materials. We also enable you to choose between different cleanliness levels in production: optical requirements in display technology, high-voltage, microelectronics applications, sensor technology or medical applications.

Pressure compensating elements and membranes

These elements balance out differential pressures and also reliably prevent the ingress of humidity and dirt. These press-balancing membrane elements from SCHLÖSSER can for example be used in vehicle ECUs. What can we offer you? A wide selection of different membrane materials catering for different airflow rates and resistance to a broad range of media. In addition, diameters or desired component contours can be adapted individually – even for small volumes. Also, each adhesive film can be defined specifically to suit your requirements and those of the adhesive mating part. We can supply these in the form of classic self-adhesive membranes, on adhesive strips or as a clamping variant.
