CNT Testing of planar and molded materials is performed in the RMV Tech Group ESD laboratory.
Care must be taken in the handling and testing of CNT materials in the powder substrate.
Due to issues with "hot spots" in the planar form, RMV has developed a trade secret method of Mapping the substrate for a complete report of ESD performance.
CNT materials improperly handled during the extrusion process can develop hot spots. Another area for the formation of hot spots occurs in the vacuum forming or injection molding process.
When testing CNT materials, we recommend that the customer provide both a planar substrate as well as a vacuum formed or injection molded sample for ESD performance of a CNT material.
