AEROSIL® fumed silica—packaging

Standard packaging

AEROSIL^® products are supplied in a multi-layer paper bag and are equipped with an additional polyethylene coating , if required. The net weight of these bags ranges from 10 kg to 20 kg (also 10 lbs in NAFTA), depending on AEROSIL^® types and their corresponding tapped density.

Flexible Intermediate Bulk Container (FIBC)

Evonik also delivers AEROSIL^® products in FIBC packaging -. These are flexible containers made of woven polypropylene fabric, with 4 loops attached to the upper corners for lifting purposes. The discharge spout to empty the container is located in the center of the b ottom and is adapted to fit Evonik's uniquely-designed powder emptying system (PESy). This system is available to our customers and enables a simple and dust-free emptying of our product. The quantity delivered varies according to the product.

Silo transport

When large amounts of AEROSIL^® fumed silica are required, delivery by silo transport is another option. While silo truck is standard practice in Europe and Japan, the use of railroad silo wagons prevails in NAFTA. Bulk delivered quantities vary by transport equipment and product.

Thermal packaging for AERODISP® dispersions

AERODISP^® dispersions are available in 60 kg canisters, 220 kg drums, and in 1000 kg intermediate bulk containers, IBC (totes). Depending on the region, additional thermal insulation packaging is used.

Compaction technology

Certain AEROSIL^® grades are also available in a compacted form under the names AEROSIL^® V and AEROSIL^® VV. The densification process is carried out by means of a vacuum combined with mechanical pressure. AEROSIL^® V and AEROSIL^® VV differ from one another with respect to the compaction technology used. In the case of the AEROSIL^® V grades, the tapped densities are 90 g/l (hydrophobic) and 120 g/l (hydrophilic). AEROSIL^® VV is available with tapped densities of 50, 75, 90, and 120 g/l, reflected in their respective nomenclature (e.g. AEROSIL^® 200 VV 75).

AEROPERL® technology

Upon request, certain hydrophilic and hydrophobic fumed oxides can be delivered in granulated form. These products are manufactured using a specially-developed AEROPERL^® process. AEROPERL^® products display a high tapped density, good abrasion resistance, and a high moisture adsorption. Products manufactured according to the AEROPERL^® process exhibit excellent free-flow behavior and handling properties.
