Bisphenols

In recent years, we have developed and produced bisphenol derivatives (TBIS® Series) to meet the growing needs for high performance and high function substances.
Fluorene derivative, in particular, has been under a spotlight as a potential material for optical lens and films, organic EL elements, liquid crystal, etc., as it shows characteristics such as high refractive index and low birefringence due to its unique molecular structure (cardo structure).
We are capable of manufacturing high-quality products with utilization of our proprietary know-how we have accumulated over many years.
