Development of materials that achieve low thermal expansion (low CTE) and low transmission loss (Low Dk/Df) in the high-frequency range, as well as transparent polyimide resins!
Seika's TFMB is an aromatic diamine containing a biphenyl skeleton and a meta-position trifluoromethyl group. It is a monomer known for its rigidity due to the main chain structure and the introduction of the bulky trifluoromethyl group, making it suitable for the development of low thermal expansion resins and low transmission loss resins (Low Dk/Df). Additionally, fluorinated polyimides using TFMB have been adopted as window films for foldable smartphones, leveraging their high transparency. In addition to circuit board materials, it is also suitable for LCD/OLED materials and flexible/foldable display materials. We handle various aromatic diamines beyond those listed on our website.
