Evonik’s™ versatile SIPERNAT® range is used across a wide varierty of industries, in an ever increasing number of applications. These fine, inert precipitates are entirely inorganic and are composed of approximately 99% silicon dioxide (SiO2). SIPERNAT® has long been used to facilitate manufacturing processes and enhance the performance of end products. Its unique physical characteristics mean that it is often unrivalled when it comes to improving properties such as flowability and anticaking in powders. Additionally, SIPERNAT® is used to convert difficult to handle liquids into free flowing powders, this is particularly common in the Agrichemical industry for the production of wettable powders and water dispersible granules.

Features


    • Precipitated silica and silicate derivatives.

    • High internal pore volume.

    • A range of particle size distributions.

    • FAMI-QS approved grades available.

    • Hydrophilic and hydrophobic variants.

Benefits


    • Highly efficient liquid carrier capable of absorbing up to three times its own weight.

    • Improves flow properties and reduces effects of caking in hygroscopic powders.

    • Popular choice for antiblocking in polymer films due to spherical morphology, size and hardness.

    • Hydrophobized grades work well in boosting defoamer efficiency.

    • Cost effective IR absorption in polymer films.

Typical Applications


    • Free-flow and anticaking additive in a wide range of host powders.

    • Carrier for a wide range of liquids e.g. pesticides, fragrances, feed additives.

    • Booster for defoamer/anti-foaming agent manufacture.

    • Antiblocking agent in polyethylene film. Works well in other thermoplastics as well.

    • Matting and scrub resistant additive in decorative coatings.
