Employing our composite material technologies, we are developing new materials designed to have well-balanced properties such as their thermal conductivity and expansion rate.  Our plating technology has produced Celmet™, and we are currently developing Celmet™ composed of various alloys. This technology is also used for surface treatment of tab leads and heatspreader.

Polymer Material Technology

polymer synthesis, resin formulation, polymer alloy, nano-composite

Employing polymer synthesis and resin formulation technologies, we have been developing a wide array of products such as electric wires and cables in the fields of environment and energy, electronics, and automotive, as well as magnet wires for environment-friendly vehicles.

We are also working on the development of newly functional and high performance polymer materials through nano-sized material structure control (polymer alloy and nano-composite).
