Products

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

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

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.

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.

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.
