New Fields

  • For high functionality, we are developing nano materials for electrode materials, rubber/resin combined materials, etc.
  • Based on the Carbon Nano Tube compounded by our company, we offer dispersed fluids/wet master batch/yarn/non-woven fabrics.
  • Leveraging the differing materials joining technology cultivate for one of our main products, Cylinder Liners, we are developing various cast-in products.

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.

Nano Porous Material

Nano Porous Material is a multi-holed materials with infinite micro holes.

This development is joint research with Tohoku University using "molten metal dealloying method" on Nano Porous Material.

The molten metal dealloying method is to liquate certain elements from multi-component alloys into molten metal, to create the target porous material. The characteristic feature lying in this manufacture method is that is has continuous micro holes from the surface to the interior of the material, an ""open porous structure

By immersing a Si and Mg allow in molten Bi, the Mg is liquated into the molten Bi, forming the multi-hole Si structure (in the case of Si).
