Manufacture of carbon nanotube resin products (compounds and molded products)

HIPERSITE W series (hereinafter referred to as W series) is a carbon nanotube (CNT) resin developed based on our resin composite technology.
It is very difficult for carbon nanotubes to be uniformly compounded inside the resin, but if dispersion control can be performed, they will exhibit excellent performance.
 *Since our first commercialization in the world in 1999, we have accumulated many technologies to develop the potential of CNT, from CNT dispersion to molding processing and electrostatic property control.
 *It achieves excellent antistatic performance without losing the properties of the base resin, such as low dusting, toughness, and moldability.
 *We offer a wide range of grades from polycarbonate to PEEK to meet various requirements


Merits of W series

◇ Carbon nanotubes are fine, meandering fibrous conductive fillers made from high purity hydrocarbons.
◇ Carbon nanotubes, even with small additions, exhibit conductivity through fine networks.
◇ Therefore, there are many merits as follows compared with conventional conductive resin.
- Excellent electrostatic property (ESD)
- There are few particles in liquid, dust such as scratch.
- Less contamination with gas, ions, etc.
- Excellent in moldability because of good fluidity and toughness.
   


Merits of CNT resin

We compared the condition of the surface of the molded product of W2000 (PC / CNT) and PC / CF.
The surface of W2000 is homogeneous and there is no CNT exposure.When the surface of the molded product is removed, it can be seen that a fine CNT entanglement network is formed inside.
According to this result
○ There is no dropout of particles.
○ There is no charge or discharge.


W series electrostatic discharge (ESD) prevention characteristics

The ideal electrostatic discharge (ESD) performance is "no charge" and "low discharge".
The W series combines these characteristics.


Charge characteristics of W series

In the W series, charging does not occur even in areas with high surface resistance.This is because the W series has a fine and dense conductive network of CNTs, so there is no charge accumulation area.


Discharge characteristics of W series

The W series is able to remove the charge of a charged object reliably and quickly.The graph shows that the 1000 V charge can be removed within 0.1 seconds.


Discharge characteristics of W series

Discharge occurs when charged devices come in contact with antistatic products.This discharge generates a large current and noise electromagnetic waves that damage the device.
The W series does not cause a large discharge when grounded, and does not damage the device.
  This is because the W series conductive network is fine and precise, so there is no charge concentration site.


Surface resistance dependence of discharge characteristics of W series

Generally, the lower the surface resistance, the larger the current and noise generated by the discharge.W series discharges are very small over a wide surface resistance range.


Dusting property of W series (particles in liquid)

When ultrasonically cleaning antistatic products, the conductive filler may fall off (particles in the liquid) and contaminate the cleaning solvent or device.The W series has very few particles falling off when ultrasonic cleaning.This is because the W series conductive filler CNT is not exposed on the surface of the antistatic product.


Lineup of W series

The W series includes various engineering plastics such as polycarbonate, and also has strength and slidability improvement grades.


Application example of W series

W series, it has been used in a wide range of fields products.
