3M FC-40 氟化液
3M氟化液FC-40是無色透明全氟化學品，具有良好的化學惰性、電氣絕緣性能、熱傳導性和特別的第表面張力廣泛應用于半導體制造廠作為熱傳導介質。其液體溫度范圍為-57°C 至 155°C，主要應用于蝕刻設備、離子注入設備、測試設備及其他設備。因為FC-40是單一組分，所以其成分不好出現降解或者過期。FC-40沸點高，其隨時間的揮發也比較少。
3M Fluorinert Electronic Liquid FC-40 is a clear, colorless, thermally stable, fully-?uorinated liquid ideal for use in many single phase heat transfer applications in the semiconductor manufacturing industry. Its liquid range (-57°C to 155°C) makes it ideal for a variety of applications such as etchers, ion implanters, testers and others. Because Fluorinert liquid FC-40 is primarily a single compound, its composition will not shift or fractionate with time. This keeps fluid loss to a minimum and insures that transport properties will not change with time.
