SIPERNAT® 22 is a precipitated silica, that combines a high absorption capacity together with a good flowability. It is our basic recommendation as a carrier silica for converting any kind of liquid into free-flowing powders.
Description
SIPERNAT® 22 S is a precipitated silica engineered for high absorption capacity, part of Evonik's SIPERNAT® range of precipitated silica, aluminium, and calcium silicates. Its main role is as a flow and anti-caking agent across a wide range of formulations, and it also serves as a special-purpose ingredient in mechanical graphic papers. In plant protection formulations, 22 S is commonly selected as a carrier for wettable powders (WP) and water-dispersible granules (WG) when grinding needs to be avoided — its absorption capacity lets it carry active ingredients into a free-flowing solid form without an additional milling step. A specific food-grade quality of this grade is also available for food-contact applications.
Key Benefits
• high absorption capacity
