More than !" years of experience in theproduction, modification and applicationof fumed silica provide a sound basis forcontinuously enhancing these products.We strive to meet the increasing demandsof existing and new areas of application.Our objective is to fully satisfy ourcustomers’ expectations – now and in the future.

We invest in innovative, emergingapplications so we can share expandingmarkets with our customers. An exampleof this is the computer industry, whereAEROSIL® fumed silica has been aauxiliary material in the production ofmicrochips since the #$$"s.Thanks to the versatility of AEROSIL®products, there is always potential for usto discover new markets and applicationsthat are waiting to be discovered.

In addition to experience and the spiritof research, AEROSIL® fumed silica ischaracterized by one thing in particular:our value-added-product philosophy.This philosophy is driven by a package ofservice components which complementeach other and combine perfectly tocontribute towards achieving enormouse%ects with aggregated particles.

This package is based on excellentcustomer contact, world-wide technicalsupport and advice, as well as a consistenthigh level of product quality and supplysecurity. Additional components are:tailor-made logistics concepts to ensurereliable delivery, research & development,handling technology and, last but notleast, very detailed technical literature.On repeated occasions, this philosophyhas set new standards in the productquality of AEROSIL® fumed silica andenables us to create genuine added value for our customers every day.

AEROSIL® –More than just a powder

AEROSIL® – Products with countless possibilities

Having everything in perfect sync opens up unforeseen perspectives

%

Along with the traditional polyester,silicone, paints and coatings applications,hydrophilic AEROSIL® products are usedwith increasing success in high technology fields. The particle nature and high purityof fumed silica play key roles in theelectronics and optical fibers industries.AEROSIL® EG &" is of an especial highlypure quality and has been developed forthese applications.

Furthermore, the hydrophilic AEROSIL®grades are characterized by an X-rayamorphous structure. Depending on themarket and application, products withvarious primary particle sizes anddi%erent BET-surface areas are available.Certain types are also available incompacted form (V and VV grades)and in a pharmaceutical grade.

Numerous grades of hydrophobicAEROSIL® fumed silica have beendeveloped to solve particular technicalproblems. AEROSIL® hydrophobic fumedsilica are produced by chemical treatmentof hydrophilic grades with silanes orsiloxanes. In the finished product thetreatment agent is chemically bonded tothe previously hydrophilic oxide.AEROSIL® hydrophobic products arecharacterized, among other things, bya low moisture adsorption, excellentdispersibility and their ability to adjustrheological behavior, even that of polarsystems.

AEROSIL® grades such as R *'"",R )'"" and R $'"" undergo additionalstructural modification which makes itpossible to o%er further support toour customers in the development andenhancement of their products. An example of this would be higher loading levels in liquid systems with little impact on viscosity.

AEROSIL® fumed silica in a semi bulk container (FIBC: Flexible Intermediate Bulk Container)

Typical bag packaging of Evonik AEROSIL® fumed silica

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

Flexible Intermediate Bulk Container (FIBC)Evonik Industries also delivers AEROSIL®

containers made of woven polypropylene bands, with loops attached to the upper corners for li-ing purposes. The valve used to empty the container is located in the center of the base and is adapted to Evonik s uniquely-designed Powder Emptying System (PESy). This system is available to our customers and enables the simple and dust-free emptying of our product. The quantity delivered varies according to the product.

Silo TransportWhen large amounts of AEROSIL® fumed silica are required, delivery by silo transport is another option. While

silotruck shipment is standard practice in Europe and Japan, the use of railcars prevails in NAFTA. Bulk-delivered quantities vary by transport equipment and product.

Thermal Packaging for AERODISP® AERODISP® dispersions are available in 60 kg canisters, 220 kg drums and in 1000 kg Intermediate Bulk Containers, IBC. Depending on the region, additional thermal insulation packaging is used.

Compaction TechnologyCertain 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 di%er 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,

in their respective nomenclature (e.g. AEROSIL® 200 VV 75).

AEROPERL® TechnologyUpon 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

and handling properties.

Storage StabilityWe recommend that all AEROSIL® grades be stored in closed containers under dry conditions, protected from volatile substances and processed within one to two years a-er manufacture. AERODISP® dispersions should be protected from heat and frost and should be processed within 6 to 12 months a-er manufacturing date, depending on the grade. The date of production can be determined via the control number printed on each packaging unit.
