with particular success in PC, PC/ABS and PC/PBT compounds. Hybrids of carbon nanotubes with stainless steel fibres have given high EMI shielding results in excess of what is achieved separately. The company reports successes for its range of compounds in medical and military applications where good mechani- cal properties, recyclability, ease of manufacturing, and weight reduction were key requirements. One grade, based on a polycarbonate/PBT matrix, is used to manufacture TBA’s own bonding plug earth pin for grounding static safe working areas. It is said to provide superior strength and weight reduction. The company says its compounds are frequently
used to produce production aids for the electronics industry such as boxes, bins and PCB racks, safe handling equipment tools and instruments, static dissipating equipment housings for ATEX applications, and EMI shielding (its range includes compounds providing a level of 34dB of EMI shielding). TBA notes that the specific shear-thinning nature of nanocompos- ites makes it possible to mould the materials to the normal range of thickness for thermoplastics. Total says it received its first commercial orders for a

new range of ESD compounds containing CNTs late last year. Polystyrene and polyolefins compounds have been developed for sheet extrusion, thermoforming, rotational moulding and injection moulding. The company claims the compounds “exhibit a unique balance of cleanliness, processability and electrical performance.”
