Experience and innovative spirit

No unbonded nanoparticles

Products such as carbon blacks, silicas and titanium dioxide do not normally contain unbonded nanoparticles. These particles are present in the form of aggregates and agglomerates with diameters ranging from 20-50 micrometers to several millimeters. They are formed during the production process by the bonding of primary particles measuring less than 100 nm. That is why they are classified as nanomaterials.

Evonik’s production capacity for carbon blacks totals 1.4 million metric tons a year. These substances, which are composed of minute particles, greatly improve the performance of technical-grade rubber. For example, they are used to manufacture fuel-saving auto tires with a good grip, low rolling resistance and a long service life. They are also used as pigments in a wide range of applications including paints, inks and plastics.

Another fine-particle product manufactured by Evonik is the fumed silica AEROSIL®, which increases the elasticity and tear resistance of silicone, improves the free-flow properties of powders, optimizes the running properties and scratch resistance of coatings and is used as a polishing agent for microchips.

Innovation based on nanotechnology

Evonik is well-positioned to utilize the opportunities offered by nanotechnology thanks to decades of experience in particle technology. The Nanomaterials Project House (2000-2003) systematically extended the Group’s strong global technology platform for the production of nanomaterials. The new products developed in this Project House have now been transferred to the Inorganic Materials Business Unit.

Through Creavis Technologies & Innovation, which bundles the Group’s strategic research, Evonik systematically uses nanotechnology to gain access to new areas of business and integrate its expertise into innovative applications.
