Polycarbonate Diol (PCDL) is a high-performance aliphatic polycarbonate polymer with terminal hydroxyl groups, synthesized by transesterification or copolymerization. Compared with conventional polyester polyol and PCL polyol, PCDL owns outstanding hydrolysis resistance, oxidation resistance, ultraviolet resistance, abrasion resistance and low-temperature performance. It is the core raw material for manufacturing high-grade polyurethane CASE materials and elastomers.
