Specialty OlefinR&D product
Utilizing the manufacturing techniques we have accumulated for alicyclic olefins and special aromatic compounds, we are developing a variety of specialty olefins.
TCPD (R&D Product Name)

We are developing new classes of compounds by utilizing "norbornene chemistry" knowledge cultivated through the manufacture of DCPD and other efforts up to now. One of those we are developing is TCPD (R&D product name), a cyclopentadiene trimer. (Pilot scale)
