Hydropower

WACKER has a strong expertise in hydro power since 1914. Attention is now also focusing on innovative concepts for harnessing tidal and wave power. Our technologically advanced products provide forward-looking solutions for industrial users in wave power plants and hydro power plants.

WACKER's in-depth expertise in hydropower dates back to 1914. Now, we are also focusing on innovative concepts for harnessing tidal and wave power. Our high-tech products provide pioneering solutions for industrial designers of wave-power and hydropower generators.

In wave-power generators, ELASTOSIL® Film can be used as an electroactive polymer to harvest energy from the sea. In this application ELASTOSIL® Film serves as a dielectric medium, return spring and carrier for electrodes, ensuring durability over millions of cycles. ELASTOSIL® Film is produced from addition-curing silicone rubber grades, available in thicknesses as low as 20 micrometers. Production takes place under clean-room conditions and yields flawless, homogeneous films of extremely uniform thickness, and all with the positive properties of silicones.
