SWCNTs for conductivity in Plastics
Day one of the 10th PLASTIVISION INDIA 2017 saw Ravi Dabral said Tuball from OCSiAI is first mass- produced
an interesting talk on, ‘Conductivity in Plastics’ by SWCNT with 90 per cent global production industrial
Ravi Dabral from OCSiAI Worldwide, the acronym OCSiAI applications of Tuball include lithium-ion batteries,
translate into Oxygen, Carbon, Silcon and Aluminium – polymer composites, TCF and elastomers Expalining
four elements most used by mankind, said Ravi Darbral. why CNT for thermoplastics, he said antistatic additives
are used in floors, mats, linoleum, textile carpets, floor
In his presentation titled, ‘Redefining Materials, finishes and coatings, clothing; gloves and finger cots;
Reinventing Technologies’, he spoke of Single Wall Carbon packaging; wires and cables etc. Ravi Darbal said SWCNT’s
Nano Tubes (SWCNTs) and their properties such as being additive can impart elctircal conductivity in plastics.
