As a technology partner with more than 50 years of experience, Berghof and its customers develop products and material solutions of the high-performance plastic PTFE. Berghof’s role goes far beyond that of strict material selection. Experts advise and inspire in optimal processing of the material as well as in the development of applications and possible uses. Our experts are, of course, reliable partners in terms of system and process quality. We have aligned our quality management according to the international standard IATF 16949:2016 and submit to, and have success in, regular certifications.

Hermetically sealed housings suffer considerable fluctuations of internal pressure due to temperature changes, or altitude differences. Condensation may form and lead to corrosion. Pressure fluctuations may also damage seals. The endangered components include headlights, housings, tank containers, drive trains, batteries, engines and sensors, along with more than 40 other vehicle parts.

Berghof has developed a venting membrane for large-volume, high-voltage batteries in electrical vehicles. This is in order to compensate for the fluctuating internal pressure; protect the batteries from entering water; and permit controlled degassing in an emergency.
