Nanostrength® and Graphistrength®: nanostructured materials with extraordinary characteristics
Transforming matter at the nanometer scale
Whether they are developed according to exclusive technologies that make it possible to control their structure on the molecular level, or they are dispersed in polymer matrices, Arkema’s nanostructured materials stand out for their extraordinary characteristics, particularly in terms of mechanical properties and electrical and thermal conductivity.
Extremely high-performance applications
Nanostrength® and Graphistrength® are intended for all cutting-edge technological fields – such as aeronautics, sports, automotive, electronics, special adhesives, and tires – that demand performance above and beyond that of traditional materials.
Graphistrength® carbon nanotubes
The Graphistrength® range includes various grades of multi-wall carbon nanotubes, produced in a pilot facility located at the Lacq research center, and master batches formulated from (composed of) nanotubes dispersed in thermoplastic or thermo-setting matrices.
Nanostrength® block copolymers
Obtained via exclusive technologies based on controlled homolytic polymerization with a nitric oxide base or anionic polymerization, they are presently available in two families: MAM symmetrical copolymers, containing two polymethylmethacrylate blocks around a central butyl polyacrylate block, and polystyrene SBM copolymers, polybutadiene-1.4 and polymethylmethacrylate.
| Graphistrength® is a range of multiwall carbon nanotubes developed by Arkema. Suitably dispersed within the materials they are designed to enhance, they impart outstanding characteristics in terms of mechanical properties as well as electrical and thermal conductivity. |
 | Nanostrength® is a new range of block copolymers developed from Arkema’s exclusive technology and its controlled and anionic radical polymerization chemistry. In particular they help deliver superior mechanical strength while maintaining the properties of the matrix to which they are added. |
Preventing potential risks associated with nanoparticles
Desirous of considering the potential health risks associated with the handling of carbon nanotubes, Arkema's approach (in alignment with the opinion of the HCSP, the French High Council on Public Health) involves a focus on prevention, for both its employees and its user clients. This pro-active approach is based on three principles: protection as long as any doubt persists, acquisition of the necessary knowledge to be able to characterize any risks, and transparency with regard to stakeholders.
