We have started collaboration with Okamoto Glass Co., Ltd. for mass production of high-strength AlN composite ceramic materials.

U-MAP Corporation (Head Office: Nagoya City, Aichi Prefecture; CEO: Kenji Nishitani) and Okamoto Glass Co., Ltd. (Head Office: Kashiwa City, Chiba Prefecture; Chairman and President: Takeshi Okamoto) are pleased to announce that they have started collaboration to establish a mass production system for aluminum nitride composite materials with the addition of U-MAP’s proprietary material “Thermalnite” (fibrous aluminum nitride single crystal) using Okamoto Glass’s ceramics sheet production technology.

Okamoto Glass Co., Ltd. is a one-of-a-kind company that has three No. 1 products in the world market that it manufactures and sells, including new glass for optical devices, special glass for industrial use, and multilayer deposition products. We have been engaged in the ceramic green sheet contract and test processing business for the semiconductor and electronic components industries while expanding our glass frit products.We provide total support for our customers’ product launches, featuring small-lot production of 1 to 1,000 units.

U-MAP, Inc. is an innovative materials venture that aims to solve thermal problems through the social implementation of fibrous aluminum nitride single crystal (“Thermalnite”), which is the research result of Ujihara Laboratory (Institute for Future Materials and Systems), Nagoya University.We are developing new functional materials that can improve the heat dissipation of electronic devices in order to solve the thermal problems that reduce the performance and life of electronic devices.In particular, the high-strength AlN composite ceramic material has achieved both high thermal conductivity and high mechanical properties, and is being developed for use in power modules for EVs and trains, and in the field of optical communications.

U-MAP has already started selling samples of Thermalnite and masterbatches of Thermalnite added to ceramics, resins and rubbers to more than 70 companies.

We are pleased to announce the start of a collaboration between our two companies to study the mass production of ceramic sheets using Thermalnite.This collaboration was initiated by the Kanto Bureau of Economy, Trade and Industry of the Ministry of Economy, Trade and Industry (METI) through its participation in the “Value Creation Challenge Project through Collaboration between Small and Medium-Sized Enterprises and Startups” with the cooperation of the Tokyo Metropolitan Shinkin Bank.
