Products

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.

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.

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.

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

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.

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

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

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.

SIPERNAT® D 17 is a hydrophobic (i.e., not wettable by water) silica also used in defoamer.

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.

AEROXIDE® TiO₂ P 25 isa fine-particulate, pure titanium dioxide (TiO₂) with high specific surface area and marked aggregate and agglomerate structure. Because of its high purity, high specific surface area, and unique combination of anatase and rutile crystal structure, the product is suitable for many catalytic and photocatalytic applications. Its structure also makes it suitable for use as an effective UV filter.

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

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

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

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.
