Products

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

SIPERNAT® 45 S is a carrier silica with high absorbency that finds typical applications in rubber and plastic additives, plant protection formulations, and feed additives. Its benefits include improved flow properties in fine particle applications, faster production rates, and increased capacity.

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

SIPERNAT® 45 is a high-absorbency carrier silica that is capable of converting liquid active substances or solutions into powders. It has the ability to produce concentrates with up to 75% concentration. This carrier silica finds typical applications in rubber and plastic additives, plant protection formulations, and feed additives.

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® 200 is a hydrophilic fumed silica with a specific surface area of 200 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.
