WEB EXCLUSIVE: In one of two recent announcements about carbon nanotubes, Arkema Inc., Philadelphia, has received EPA approval for commercial sales of its Graphistrength carbon nanotube (CNT) masterbatches in the U.S. These products are already commercially available in Europe and Asia. They are aimed primarily at electrostatic dissipation (ESD) in automotive and electronics applications. Grades containing 20% or 30% multiwall CNT in nylon 6, 66, 11, or 12 as well as a “universal” masterbatch for nylons, TP polyesters, and PC, and a multipurpose grade for PVC, ABS, other styrenics. Arkema also offers Graphistrength masterbatches for various rubbers, and both liquid and solid versions to strengthen epoxies (liquid versions sold by Zyvex Performance Materials, Columbus, Ohio. Meanwhile, engineering stock shapes producer Quantum Polymers, Newark, Del., has introduced Quantano extruded rods and plates of carbon nanotubes in PC, PEEK, PEK, ETFE, PEI (Sabic’s Ultem), and TP polyimide. The materials used to extrude the shapes are from the “TEGO polymers” family of nanotube compounds formulated by Entegris, Billerica, Mass. Entegris uses proprietary technology to enhance dispersion of the nanotubes and achieve very consistent ESD properties.
