As a technology leader focusing on sustainability, WACKER promotes products and ideas that offer high value-added potential to ensure that current and future generations enjoy a better quality of life based on energy efficiency and protection of the climate and environment.
WACKER’s forays in the energy sector focus of photvoltaics, solar thermal energy and wind power.
Wacker’s Energy Solutions
A very important pillar towards climate-friendly energy production, WACKER believes that photovoltaics is a segment that needs to be expansively researched and pioneering, competitive products developed by manufacturers who want to keep a crucial lead over their competitors.
As a leading supplier of raw materials, WACKER has been an important partner of the solar industry for many years. In addition to hyperpure polysilicon, the starting material for crystalline solar cells, the Munich-based chemical company also produces silicones which are used as potting materials, adhesives and sealants or encapsulants in solar cells and modules.
WACKER is one of the largest silicone manufacturers in the world and has decades of experience in the field of silicone chemistry. Its ELASTOSIL® Solar and TECTOSIL® brands offer a wide range of specialty products for the photovoltaics industry. As a leading manufacturer of polysilicon and silicones, WACKER is widely sought-after as a partner in the development of innovative materials to increase the efficiency of photovoltaics.
WACKER offers module manufacturers an integrated package for encapsulation, potting, bonding and special applications in the form of TECTOSIL® silicone-based thermoplastic and the ELASTOSIL® Solar product range.
Photovoltaic Solutions offered by WACKER include:
- Ensuring integration of the different module components
- Fixing the mounting systems of frameless large modules
- Protecting sensitive solar cells against weathering and moisture
- Insulating electrical components in the junction box against the most diverse of external effects
- Focusing sunlight on concentrator cells
WACKER also offers ESA-approved specialty products from its ELASTOSIL® S range; a range which has properties specifically designed for outer space, for extraterrestrial applications.
Solar Thermal Energy
Solar-thermal systems are used for sustainable energy recovery, and make high demands on the materials used, which must first and foremost be resistant to weathering, radiation and heat.
Building on the fact that silicone products are especially suitable for specific applications in harsh conditions, WACKER has developed ELASTOSIL® solar self-adhesive silicones, which ensure permanent bonding between the glass cover and the collector housing.
Highly heat-stable WACKER silicone fluids AK and AP, as heat-carrier fluids, effectively remove the energy collected, and remain liquid even at low temperatures.
WACKER silicones are used in the economic exploitation of wind power, and are impressive for their high resistance to extreme temperature shocks, weathering and environmental effects, as well as their versatility of processing:
- for encapsulation of sensitive electrical components
- for use in various sealants and adhesives
- for cooling and for electrical insulation of novel high-temperature operating transformers
- for the production of composite materials by means of reusable silicone system solutions
- The wind turbines of windmills consist of composite shells that are bonded together. HDK® pyrogenic silica is used to control the rheology of the widely used epoxy or vinyl-ester adhesives
