Products

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® 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 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.

ZEOFREE® 80 is a finely milled, hydrophilic silica. It is primarily used as a free-flow agent in other applications. ZEOFREE® 80 can also be used in-situ hydrophobized in defoamers. The use of an alkaline catalyst is recommended.

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® 22 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.

AEROXIDE® Alu C 805 is a fine-particulate, fumed aluminum oxide (Al₂O₃) that is highly hydrophobized with an organosilane.

SIPERNAT® 28 is a very finely milled, hydrophilic silica. It is primarily used as a thickening or free-flow agent in other applications.

SIPERNAT® 50 is a hydrophilic, coarse silica with the highest absorptive capacity and a high surface area. It is capable of transforming any liquid solution, water- or oil-based systems into dry powder concentrates of up to 75%.

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.

SIPERNAT® 823 is a finely milled, hydrophilic sodium aluminum silicate. It is primarily used as a free-flow agent in other applications.

SIPERNAT® 340 is a medium sized silica with spherical particles and high oil absorption capacity (DBP). Is less dusty than small particle size flow agents, yet still gives good free flow improvement performance.
