Silicone sealing and bonding solutions for the energy industry
Empowering the future of efficient energy production, distribution and consumption
Never in the history of humanity has energy played as crucial a role in our societies as it does today and never has it been as central to the way we envisage our future. Energy sources are today more diverse and abundant than ever and are at the heart of our economic, ecological and political debates. While trying to manage and potentially reduce our dependence on traditional fossil fuels such as oil, gas and coal, most countries are attempting to find the right balance between economic development, energy efficiency, independence and environmental responsibility.
Silicone reusable vacuum bag for composite windmill blades
Reusable Vacuum Bag (RVB) silicone membranes improve the quality in composite molding.
Fiber reinforced polymer (FRP) composites are increasingly being used to make molded parts for a wide variety of industries: automotive (including trucks and off-road vehicles), renewable energy (components such as wind-power propellers), aerospace, marine construction, architectural structures, etc. These composites combine excellent mechanical properties with a low density, and feature high resistance to water, chemical and environmental pressure.
Foundry alloys for ductile iron used in wind turbine engines
Controlling spheroidal graphite formation with foundry alloys
Ductile iron is a versatile material that has grown in popularity over recent decades, due to its excellent mechanical properties and castability. For these reasons, ductile iron castings are the preferred choice in many sectors, including wind energy, engineering and automotive industries. At Elkem we provide an unbeatable combination of quality products and expert advice on ductile iron manufacture – in whatever country you’re operating.
Microsilica for concrete used in windmill foundations
The construction industry is constantly seeking ways to improve the durability and sustainability of concrete structures. Since the early 1980s under the MICROSILICA® brand, Elkem has developed a unique range of silica fume products to improve the performance and durability of concrete.
Silicone coatings for composites manufacturing used in wind turbine manufacturing
Silicone pressure sensitive adhesives (PSA) are commonly used by composite manufacturers in the automotive industry for bonding various parts such as body panels, hoods, and spoilers. They provide an instant bond with excellent resistance to heat, chemicals, and UV radiation, allowing for a more efficient production process. PSA can be used to attach composite panels to a metal frame, bond different layers of composite material together, or attach accessories such as spoilers or body kits. It also allows for easy removal without leaving a residue, which is useful during the assembly process. In summary, silicone PSA is a versatile adhesive that is ideal for composite manufacturing in the automotive industry due to its ability to adhere to different substrates, resistance to heat and chemicals, and easy removal.
