Arkema extends range of Graphistrength® multi-wall carbon nanotube masterbatches

28 October 2011 by claire.smith

Graphistrength® C W1-20 is a Multi Wall carbon Nanotubes (MWNT) masterbatch that contains perfectly dispersed MWNT at a concentration of 20% by weight.

Graphistrength® C W1-20 is suited for the production of e;ectrically conductive water-based formulations.  It is based on a non-ionic water-soluble polymer that makes it compatible with most pH sensitive formulations.  This masterbatch is intended for use in electrostatic discharge (ESD) protection or mechanical reinforcement of composite structures.
Graphistrength® C W1-20 is generally diluted in various liquid bases of water-based formulations.  Typical final MWNT loadings in the final formulations are in the range 0.1 to 2 wt% depending on the host matrix characteristics, the targeted performances, processing methods and conditions.

The typical electrical resistivity that can be achieved is in the range of 10²-10ohm.cm, depending on MWNT loading and formulation.  The ESD properties obtained with Graphistrength® C W1-20 are outstandingly consistent and uniform. 

Graphistrength® C W1-20 offers particular advantages for the formulation control due to high concentration of MWNT.  It also offers a process advantage, with the possibility to efficiently introduce MWNT using conventional mixing equipment, such as impeller or high-shear mixer.  Graphistrength® C W1-20 is particularly suited for water-based paints, coatings and composites applications.
