Evonik is the inventor of AEROSIL® fumed silica, which is a synthetic fumed silica that is produced by flame hydrolysis. For over 70 years AEROSIL® has proven to enhance performance in many markets and applications. Today Evonik's AEROSIL® portfolio covers a broad range of surface areas, as well as very different surface chemistries. Also, AEROSIL® does not get tired in finding new markets, applications and effects. AEROSIL® is invented to improve.

VISIOMER® Specialty Methacrylates offer an innovative way to customize product properties for various end use applications. With a range of alkyl/aryl (meth)acrylates, aminofunctional monomers, methacrylamides, ether methacrylates, crosslinkers, HEMA for contact lenses, wet adhesion monomers and specialty intermediates, VISIOMER® has become a trusted partner in designing customized products to meet specific needs.

Evonik is one of the leading producers of nanostructured metal oxides. These are highly pure aluminum oxides or titanium dioxides. Evonik's portfolio also consists of a growing range of hydrophobic and mixed oxides grades. AEROXIDE® fumed titanium dioxide and aluminum oxide products are applied in a wide range of markets and applications such as anti-blocking agent in PET films and heat stabilizer in silicone rubber. Evonik's experienced global Applied Technology team keeps developing new applications in close collaboration with customers.

CHROMATOCEL is a normal phase alumina and silica gel used in liquid chromatography, batch extractions and decolorizations. Optimized particle size, surface area, pH, and purity make them particularly useful materials for separation of small molecules, peptides, lipids, alkaloids, acrylic monomers and a variety of other materials.

VERSALINK® are low-reactivity aromatic amines for use in polyurea or polyurea-polyurethane hybrid formulations. They can be liquid-processed at room temperature with monomeric and polymeric MDI or TDI prepolymers as well as other diisocyanates and diisocayanate prepolymers. Pot life values can be controlled and are typically in the range of 1-45 minutes, depending upon the specific VERSALINK® and isocyanate used. VERSALINK® products are specialty polymeric, non-toxic diamines that can be used as curatives and chain extenders. The range consists of varying molecular weights for use in highperformance polyurethane, polyurea and polyurea-hybrid applications. They can be processed as a liquid and incorporated with MDI and TDI/MDI prepolymers to improve final performance properties. Formulations using our VERSALINK® curatives combine the high performance of polyurea with the ease of application due to the extended pot-life and application time

ROHACELL® structural foam has been offering the aerospace and automotive industries, medical technology, and other markets boundless possibilities for lightweight construction of parts or products made from high-performance composites. In such applications ROHACELL® foam core, which is based on polymethacrylimide (PMI), is used as a core between, for example, CFRP facings or as a mandrel.

Tekucel™ high purity alumina supports for catalysts used in fluidized beds. Tekucel – Joining performance and Economics while allowing tailored final specifications. Commercially available alumina that can be economically used in fluidized bed reactors Tekucel™ is a > 99.5% pure gamma phase alumina microsphere used in oxychlorination, propane dehydrogenation and other markets. Catalysts are loaded onto Tekucel™ and then used in fluidized bed reactors.
