Description Carbon Nanotube Masterbatches CNT-PP-15 Our carbon nanotube masterbatches CNT-PP-15 use our industrial grade multi walled carbon nanotubes. This product has a 15% CNTs loading ratio. The CNT-PP-15 material can be used with 3D printers, molders, & extruders. Once received, you simply let it down and run it in your equipment. Sold by the kilogram Product Code Matrix Resin Matrix Resin Loading CNTs Code CNTs Loading CNT-PP-15 Homopolymer PP 85wt% IGMWNTS 15wt% CNTs were dispersed into PP 300 using twin-screw extruder, then the specimens were made by compression molding. Volume and surface resistivity were measured by high insulation resistance instrument ZC-90D（IEC 60093-1980, the test voltage is 100V）. CNTs Loading（wt%） 1.5 2 Volume Resistivity (ohm.cm) >1014 3.3×106 Surface Resistivity (ohm) 1.6×1013 2.2×106 CNTs were dispersed by PP SP179 (copolymer, izod notched impact strength is about 40~45 KJ/m2) using twin-screw extruder, then the specimens were made by injection moulding. The standard of mechanical property of specimens was ISO 527, ISO 180 and ISO 178.
