Carbon Nano Tube

The TPR-made Carbon Nano Tube has long length, and is a Carbon Nano Tube that has been controlled to a few layers.

The manufacturing method is highly-efficient growing of the Carbon Nano Tube perpendicularly from a large-surface area base board, and TPR has established mass-production technology.

Item	CNT length	CNT diameter	Specific surface area	Number of layers	Metal impurities	G/D ratio *
Representative value	Up to 2 mm	5 to 12 nm	225～390 m²/g and up	3 to 7 layers	Up to250ppm	0.8 and up

G/D ratio can be set to match the customer's request

Application

横にスクロールできます。

Characteristics	Aim for the material	Our joy when an application is identified
Long	Physically networked form, with few connections. High purity (few metal impurities)	Low resistance/high strength High durability
Few layers (light)	Function can be vested with small amount of additives	Just 0.1 weight % additives manifests function

Carbon Nano Tube application technologies are being developed too, and it is possible to support customer product applications.
