The resource efficiency megatrend is the basis for energy-efficient and environment-friendly products and therefore a key factor in the development of this segment's business. The Resource Efficiency segment has integrated technology platforms for silicon and isophorone. Its core competencies include the production, design and structuring of the specific surface properties of inorganic particles based on silicon oxides and metal oxides. It supplies high-quality additives, for example, for paints, coatings, adhesives and sealants. It also produces high-performance additives for oil and hydraulic fluids. In addition, Resource Efficiency specializes in custom-tailored high-performance plastics and has entered new growth markets in recent years thanks to innovations in the hydrogen peroxide business. The Silica Business Line, which bundles Evonik's activities in the area of silica products, has a very robust business base thanks to its broad spectrum of its end-markets. Precipitated silicas are mainly used in energy-saving tires with low rolling resistance ("green tires"). In addition, our portfolio of precipitated silicas includes advanced products for the food, cosmetics and pharmaceutical industries, for example, to improve the flow properties of powders and clarify liquids. Thanks to the production process, AEROSIL® fumed silicas have an enormous surface area which can be tailored to specific requirements, making them suitable for a wide range of applications. Water-repellent (hydrophobic) types are excellent insulating materials and are also used to produce scratch-resistant coatings and plastics, and tablets containing advanced active pharmaceutical ingredients. Special hydrophobic silicas and metal oxides are used to regulate the electrostatic properties of toners to optimize resolution and improve the sharpness of printing. Hydrophilic fumed silicas are mainly used in the food and cosmetics sectors because of their reinforcing and thickening properties. Another application for AEROSIL® is chemical mechanical polishing of semiconductors in the electronics industry. The Silanes Business Line produces a wide range of specialty silanes for different end-markets. For example, ultrapure chlorosilanes are used in optical glass fibers and electronic applications. Based on our integrated technology platform for silicon, we refine ultrapure chlorosilanes to produce organofunctional silanes, which modify the surface properties of inorganic particles, polymers and resins. Functional silanes are used in adhesives, sealing compounds, insulating materials and as additives in paints and coatings. An important area of application is the protection of buildings, for example, against corrosion and graffiti. This business line's third product group is rubber silanes, which are used with our precipitated silicas in energy-efficient tires with low rolling resistance. Evonik is the only manufacturer that offers the tire and rubber industry both key components for silica-silane systems, which reduce rolling resistance and fuel consumption by up to 8 percent compared with conventional automobile tires. The product portfolio of the Catalysts Business Line comprises a wide range of catalytic systems. These are used for selective and cost-efficient production of active ingredients for pharmaceuticals and agrochemicals, and fine and industrial chemicals. A large proportion of this business line's catalysts is produced for internal use and therefore plays an important part in process innovations in the Evonik Group. Active Oxygens produces hydrogen peroxide at twelve sites on all continents and is the global number 2 in this field. The market for this environment-friendly oxidation agent is developing particularly fast in Asia. This is attributable to a wide range of new applications that extend well beyond the traditional market in the paper and textile industries. For example, in collaboration with the engineering firm ThyssenKrupp Industrial Solutions, Evonik has developed an economically viable and environmentally compatible process technology for the production of propylene oxide with the aid of hydrogen peroxide: the hydrogen peroxide to propylene oxide (HPPO) process. Propylene oxide is a precursor for polyurethane, which is used in particular as an insulating material in the construction and refrigeration industries, and in instrument panels and cushioning in the automotive industry. Evonik is the only company that can supply the process technology for the HPPO process together with the necessary catalyst and hydrogen peroxide. Other applications for hydrogen peroxide are the treatment of wastewater and exhaust air. In addition, ultrapure hydrogen peroxide is used to clean silicon wafers in chip production. High-performance additives marketed by the Oil Additives Business Line improve the lubricating and flow properties of engine oils, hydraulic fluids, fuels, biodiesel and industrial fluids. In this way they improve fuel efficiency, i.e. they reduce fuel consumption and CO2 emissions. Thanks to many years of close collaboration with well-known lubricant manufacturers and automotive OEMs, this business line has developed specialist expertise in engines, gears and hydraulic systems. Customers benefit from this through custom-tailored high-performance additives and an extensive range of technical services. Evonik is the market and technology leader in isophorone chemistry and the only company in the world that covers all processing steps. The production of high-performance, isophorone-based crosslinkers is the core competence of the Crosslinkers Business Line. Isophorone diamine increases the service life of heavy-duty surfaces, which cuts maintenance costs and often makes refurbishment unnecessary. Examples are floor coatings in parking garages, facades that have to withstand tough climate conditions and ships that are constantly exposed to salt water. Isophorone diamine-based composites are used, for example, to increase the resistance of wind turbines and make automobiles lighter. Isophorone diisocyanate is used in the production of light-, weather- and temperature-resistant polyurethane binders and is therefore a key component in many environment-friendly coating technologies. The Coating Additives Business Line specializes in application-oriented solutions for coating technologies, e.g. for use in lacquers, paints and inks. Its product portfolio ranges from additives and co-binders to specialty resins and nanoresins. The TEGO® brand comprises a wide range of additives for innovative coating formulations. The Coating Additives Business Line has outstanding knowledge of how to influence rheology and surface properties, which play an important role in coating technology. Its extensive competence in paints and global distribution network enable it to offer customized solutions for customers around the world. Evonik's Coating & Adhesive Resins Business Line produces high-quality binders. These are mainly used in coatings for metal packaging, protective coatings and industrial floors. In addition, this business line supplies the adhesives industry with polymers for melt adhesives, and sealing and insulating compounds, which are marketed, for example, to the automotive and packaging industries. It is systematically expanding future-oriented areas of business around the world, for instance road markings and structural adhesives for the automotive industry. The High Performance Polymers Business Line is our specialist for customized solutions with high-performance polymers. It is the world's only manufacturer with an integrated technology platform for the production of polyamide 12, which it supplies, for example, to the automotive and electronics industries. In addition, the business line has successfully gained a foothold in new markets with additives for gas and offshore oil pipelines. Its product range also includes materials for high-tech applications such as the high-temperature polymer VESTAKEEP® PEEK, which is characterized by exceptionally high heat distortion resistance, high mechanical stability and rigidity, making it an attractive alternative to metal. VESTAKEEP® PEEK and the lightweight polyimide foam ROHACELL® are both used in the construction of planes. SEPURAN® membrane modules made from hollow polyimide fibers allow cost- and energy-efficient purification of crude biogas to produce biomethane.
