The Story of Fluorine ❶ A Basic Gas Recent External Presentations

We strive to generate innovation through mutual activities which transcend both internal division lines and also the What exactly is fluorine? framework of Daikin itself. We will introduce some of the research presented at TIC between October 2015 and November 2016. Through this, we aim to encourage new themes of collaboration for technology development.
