U-MAP's World-class technological capabilities
The synthesis technology of Thermalnite (fibrous aluminum nitride single crystal) is one and only proprietary technology in the world.It is a filler material with both high thermal conductivity and insulation properties.
U-MAP has established a high-quality, high-volume synthesis technology for Thermalnite.
We are developing Aluminum Nitride Composite added with Thermalnite. U-MAP`s ceramic composites have high mechanical and also the high thermal conductivity.We are developing this product focusing to expand into the field of power modules for EVs and trains, as well as the field of optical communications.
We are developing high thermal conductivity resin/rubber composites containing Thermalnite. Conventional high thermal conductivity materials are filled with 60% to 90% filler material in resin/rubber, but Thermalnite can achieve the same or higher thermal conductivity with only 10% to 20% filler. Due to the small amount of filler material added, the resin properties (flexibility, adhesiveness, lightness, etc.) can be maintained and a wide range of molding methods can be used.
In the field of materials, various parameters such as synthesis temperature, raw material ratio, and processing conditions mutually affect each other's properties, and a huge amount of time is required to search for the optimal process. We, in collaboration with Nagoya University, are working on data-driven materials development using machine learning. By utilizing an algorithm called Bayesian optimization and other methods, we have succeeded in deriving optimal conditions in the Thermalnite synthesis process with a small number of experiments.
