Polycarbonatediol(PCD) is a linear polycarbonate with hydroxyl groups at both ends. It easily reacts with isocyanate compounds (e.g. MDI, TDI, IPDI, H12MDI) and generates polymers with superior characteristics described below. The proprietary manufacturing technology of Mitsubishi Chemical Corporation (MCC) enables production of unique composition and higher molecular weight PCDs with stable product qualities. The resins made from MCC’s PCDs "BENEBiOL™" have unique properties that existing resins have not been able to establish. In addition, some of the PCDs’ raw materials are biomass-based.
