Shaping a Sustainable Future

Research on Elastomer Seals for Hydrogen Applications

Angst+Pfister is doing research on elastomer seals for hydrogen applications, the energy of the future. To investigate the best elastomeric materials and verify which are most suitable for which function, a test plan has been established to evaluate the performance of the compounds in terms of permeation, leakage and RGD to ensure that the demanding requirements of sealings in hydrogen applications are met. In 2023, 90 Shore A H² sealing materials have been tested for permeation, leakage and rapid gas decompression in 100% H² ; 70 Shore A materials have been tested for permeation and certified according to DVGW ZP 55101-01.

Research into Extending the Durability of Dynamic Seals

Angst+Pfister tests innovative materials on an in-house-developed, state-of-the-art testing machine. In collaboration with an established university, Angst+Pfister has developed and built this versatile testing machine for dynamic seals in its Innovation Laboratory. The machine is compatible with various media and oils and enables the lifetime testing of dynamic seals at up to 15,000 rpm. As a globally active developer and manufacturer of high-performance components we have thus been able to further expand our expertise in the area of material sciences. Depending on the customer need, various seal geometries can be tested and the raw conditions (for example extreme temperatures or high pressure) under which the seals are used can be simulated.

Engineered Solutions for E-Mobility Systems


E-mobility systems are an important factor for realizing the energy transition in transportation vehicles on our decarbonisation path. Angst+Pfister supports this technology trend significantly and some of our solutions are already in daily use and part of many e-mobility applications:
 

• Engineered moulded rubber parts to provide sufficient sealing in charging connectors 
• Engineered sealing solutions in special rubber compounds for usage in the battery circuit of electrically powered vehicles 

We will continue to enable e-mobility applications with our engineered sealing solutions, contributing to the sustainable development of the automotive industry.

Investments in Innovative Technologies of Synhelion

Synhelion converts sunlight into fuel. The company has developed a unique technology to produce sustainable solar fuels from energy. Angst+Pfister has made an appropriate investment to support Synhelion in its efforts towards clean and sustainable transportation.

Broad Engagement at Innovation Park Zurich


To further promote the joint development of expertise, Angst+Pfister became one of the first members of the Innovation Park Zurich, the new Swiss platform for research, development and innovation fostered by the collaboration between primary science institutions and business sectors. Some outstanding work has already been done in collaboration with various companies and universities.
