Products

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

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

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

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

AEROSIL® R 805 is a high thickening fumed silica surface treated with OCTMO.

AEROSIL® R 816 fumed silica powder offers an alternative technology to stabilize oil/water emulsions. Due to the special surface modification of the silica both hydrophilic and hydrophobic properties are introduced in just one material. This enables AEROSIL® R 816 to enrich at oil/water interfaces and thereby stabilize oil droplets in a continuous water phase by the Pickering effect.Furthermore, AEROSIL® R 816 brings structure to the continuous water phase and increases its viscosity which limits the mobility of the oil droplets, thereby providing for even more emulsion stability.
