Bühler PARTEC and Brenntag Schweizerhall collaborate to market Carbon-Nanotube Dispersions

11/05/2007 Basel/Uzwil, 5. November 2007 – Bühler PARTEC, a company active in nanotechnology, and Brenntag Schweizerhall, provider of specialty and bulk chemicals, are collaborating to bring the value of Carbon Nanotubes (CNT) to the market. The collaboration involves the development and production of tailor-made CNT dispersions by Bühler and their marketing and distribution by Brenntag Schweizerhall. Nanotechnology is one of the key technologies of the 21st century. Among the many nanostructured materials Carbon Nanotubes (CNT) are of special interest as they are used to manufacture mechanically reinforced composites, as well as electrically conducting materials. CNTs are molecular carbon fibres with a diameter of approx. 10 nm and a length of up to several µm. Due to the fibrous structure and the nanometer size, the incorporation of CNTs into liquids, resins and polymers to improve mechanical or electrical properties of materials and products is a major challenge. The difficulty in processing CNTs has so far impeded the widespread use of these intriguing nanostructures in industry. Through the collaboration of Bühler PARTEC and Brenntag Schweizerhall ready-to-use, customised CNT dispersions will become generally available to the market.

As a provider of specialty and bulk chemicals, Brenntag Schweizerhall continues to provide cutting-edge materials to its customers and knows the specific needs of the market. Brenntag relies on its established infrastructure for the worldwide distribution of chemicals. Bühler PARTEC applies its unique know-how in dispersing nanomaterials to develop CNT dispersions according to the specifications provided by Brenntag Schweizerhall’s customers. Bühler PARTEC and Brenntag Schweizerhall are convinced that the collaboration enables the development and launch of unique products with significant value for industry and customers.

Bühler PARTEC, a business unit of the technology group Bühler AG, is a leading solution provider in nanoparticle dispersion technology. Bühler PARTEC is specialised in processing and refining nanoparticles and in the manufacture of ready-to-use nanoparticle dispersions.
