With a unique range of both hydrophilic and hydrophobic grades available the number of applications are endless. Fumed pyrogenci silica is composed of synthetic silicon dioxide SiO 2 which is entirely amorphous, eliminating the risks posed by crystalline silica. One of the main applications for fumed silica is increasing the viscosity, pseudoplasticity and thixotropy aerosiil a wide range of liquid systems.

However there are many more applications besides this common use case. Read on to find out more about this exciting product range. Efficient rheology control in a wide range of simple and complex liquid systems. Stabilises pigments and prevents sagging. Provides effective free flow and anti-caking behaviour.


Can be used as a solid carrier for liquids. Improves anti-corrosion performance of protective and marine coatings. Reduces moistures sensitivity and increases hydrophobicity. Useful in silicone sealants for extending shelf life for example.

A brief overview of the key grades is given below. Should you not find what you are looking for here then please note that we have further grades available besides these. One of our Technical Sales team will be happy to help.


All of the sales team are technically qualified and will be able to advise you on which product to choose.

A sample can be requested via the button at the top of the page as well. Please note that by providing us with your contact details, you are agreeing for us to potentially contact you.

Hydrophilic surface with a medium-high surface area. It is one of the most widely aerowil grades of fumed areosil. Efficient pseudoplastic rheology build and thixotropic behaviour in a wide range of polar and non-polar solvents and polymers. You will find some of the key aerosl brochures available for download below. There are more brochures available upon request. If you would like to discuss your enquiry further then please get in contact by phone or by filling in the “Request a Callback” form at the top of the page.

Someone from the technical sales team will then call you within 24 hours, to discuss your project further. Something of a reference manual it goes through the manufacturing process, properties of the grades, application related effects and more.

If you are interested in learning about the range in detail then this is a very useful document. Read on for more information.

Please note that there are more grades than these available however these form the core of the range. How can we assist you today? Please fill out the short form below and one of our technical sales team will be in touch within 24 hours. If it is urgent then please call us on Features Chemically inert synthetic amorphous silica. Available in hydrophilic and surface-treated hydrophobic grades. A wide range of surface areas available.

AEROSIL® fumed silica

Thickening of PAO polyalpha-olefin base oils used in cable gels. High surface area hydrophilic fumed silica.

Optimal dispersion results in pronounced thickening of a wide range of liquids. Excellent transparency in unstaurated polyester resins. Highest surface area hydrophilic fumed silica. Best in-class thickening and thixotropy ksds dispersed properly in liquid systems. Excellent transparency in unsaturated polyester resins. Imparts shear-thinning behaviour and thixotropy. The importance of rheology in epoxy resins As a formulator of epoxy resins, you know that rheology control is an important consideration when designing a system.

Take proper care over the rheology profile and you will have a product that resists sedimentation, has excellent shelf life stability, Technical Sales and Marketing Manager.
