Japan’s Mitsui Chemicals, Inc. (MCI) has launched a new grade of dust-reducing, high-antistatic nanocomposite consisting of thermoplastic polyimide and carbon nanotubes.
The nanocomposite is cooperatively developed with Hyperion Catalysis International, Inc., U.S.A. under the trade name AURUMTM CNT Grade.
MCI is the only manufacturer of thermoplastic polyimide in the world and is used for applications such as automotive parts, aviation engine parts and the processing jigs for semiconductor manufacturing by leveraging its characteristics. The new AURUMTM CNT Grade will be commercially available in April this year with the projected annual sales of at least ¥300 million by Fiscal 2007.
Among the applications for automotive parts, the processing jigs for semiconductor manufacturing as well as electrical/electronic parts, the super-engineering plastics with the addition of carbon black or carbon fibre are used as conductive materials (antistatic materials) for the applications which require high-antistatic characteristics against static electricity. The newly developed AURUMTM CNT Grade with carbon nanotube has dust-reducing characteristics in comparison with the conventional antistatic materials. Therefore, the new Grade is viewed with an expectation of applications such as the processing jigs for semiconductor manufacturing, where higher cleanliness is required.
AURUMTM CNT Grade has the following characteristics:
Its electric conductivity can be controlled, which is not possible for the conventional antistatic materials.
Superior dispersibility of conductive additives in the polymer matrix, flowability and dimensional stability, which originate from the reduced amount of conductive additives.
MCI intends to further accelerate new products and applications development in the field of Functional Polymers in order to foster the business as the mainstay of revenue toward expanding and growing the Performance Materials sector.
