Products

SIPERNAT® 22 S is a finely milled, hydrophilic silica. It is primarily used as a free-flow agent in other applications. SIPERNAT® 22 S can also be used in-situ hydrophobized in defoamers. The use of an alkaline catalyst is recommended.

AEROSIL® 200 HV is a hydrophilic fumed silica with a specific surface area of 200 m²/g.

SIPERNAT® 50 S is a hydrophilic, finely milled silica. Besides its application as flow aid and highly effective anticaking agent it also may serve as carrier of especially high absorptive capacity in case particle fineness is required.

SIPERNAT® 22 LS is a very finely milled, hydrophilic silica. It is primarily used as a free-flow agent in other applications.

AEROSIL® R 202 is a hydrophobic fumed silica grade, treated with a polydimethylsiloxane. This product can be used in defoamer formulations for sedimentation stabilization and due to its high hydrophobicity as defoaming component.

AEROSIL® R 812 S is hydrophobic fumed silica grade treated with HMDS (Hexamethyldisilazane). It is even more hydrophobic than AEROSIL® R 812 and convenient for stabilizing a defoamer and well suitable as a component of foam control agents.

AEROXIDE® Alu C is a fine-particulate, pure aluminum oxide (Al₂O₃) with high specific surface area and marked aggregate and agglomerate structure. Because of it high purity and low water content, the product can be used well as an additive to anorganic materials, for heat insulation, and also as a catalyst substrate. The positive surface charge can be used to control the electrostatic charge.

SIPERNAT® D 13 is a milled, hydrophobic (i.e., not wettable by water) silica, high methanol wettability and low surface. It is used in a great variety of technical defoamers due to its high effectiveness and ease of dispersion.

AEROSIL® R 106 is a hydrophobic fumed silica after treated with D4 (Octamethylcyclotetrasiloxane).

AEROSIL® R 8200 is a structure modified hydrophobic silica grade treated with HMDS (Hexamethyldisilazane). It is characterized by an extremely low thickening effect and high compacted bulk density. Its high hydrophobicity makes it suitable as a defoamer silica.

ZEOFREE® 5162 is a finely milled, hydrophilic silica. It is primarily used as a free-flow agent in other applications. ZEOFREE® 5162 can also be used in-situ hydrophobized in defoamers. The use of an alkaline catalyst is recommended.

AEROSIL® 300 is a hydrophilic fumed silica with a specific surface area of 300 m²/g.

SIPERNAT® 500 LS is a very finely ground silica with high surface area, low drying loss and particulary high absorbency.

AEROSIL® R 972 is hydrophobic fumed silica grade treated with DDS (Dichlordimethylsilane). The moderate hydrophobicity of these AEROSIL® products is suited for defoaming properties in the presence of appropriate hydrophobic liquids. They are recomended for improving the sedimentation stability of defoamer dispersions as well.

AEROSIL® 200 is a hydrophilic fumed silica with a specific surface area of 200 m²/g.

AEROSIL® R 812 is hydrophobic fumed silica grade treated with HMDS (Hexamethyldisilazane). It can be used for sedimentation stabilization and due to its high hydrophobicity as defoaming agent.

AEROSIL® OX 50 is a fumed silica with a very low specific surface area, low thickening, and high purity. The product can be used as an additive or as a raw material. In polymer composites, high filler loading can be achieved, making it possible to control essential characteristics of polymers.

AEROSIL® R 974 is hydrophobic fumed silica grades treated with DDS (Dichlordimethylsilane). The moderate hydrophobicity of these AEROSIL® products is suited for defoaming properties in the presence of appropriate hydrophobic liquids. They are recommended for improving the sedimentation stability of defoamer dispersions as well.

AEROSIL® 380 is a hydrophilic fumed silica with a specific surface area of 380 m²/g.

ZEOFREE® 5161 is a hydrophilic, coarse silica combining a high absorptive capacity with a good flowability. It is well suited to transform any type of liquid, including defoamers, into dry, free flowing powder concentrates.
