“Over the past few years the Nanocyl’s NC7000 product has penetrated large volume markets in thermoplastic commodities segments including automotive, electronic pacakging, and energy. Nanocyl’s MWCNT materials are typically replacing conventional carbon blacks. One reason for their adoption is that MWCNTs can add conductivity to plastics compounds at very low loadings.
Moreover, MWCNTs allow new multifunctional materials to emerge. Industrial fan blades for cooling towers in ATEX environment have been produced by Nanocyl and VAMPTECH (Italian compounder specialized in flame retardant compounds) based on a PA6/MWCNTs formulation providing multifunctional properties. These blades are dissipative (108 Ω/sq) and meet UL94 V0 flammability rating at a thickness 0,8 mm. Impact strength, elongation at break and flexural strength are at same level as currently used compounds.
MWCNTs are also ideal conductive additives for 3D printing filaments using Fused Deposition Modeling (FDM) technology. Such highly conductive filaments allow to create multifunctional tailor made components like circuits, power connectors, voltage dividers, buttons, etc. for electronics and other applications yet to imagine. Currently the mostly used grades are ABS, PA and PLA. Nanocyl provides masterbatches in ABS and PA with 15 wt.% NC7000, as well as custom masterbatches (including PLA).”
