Polycarbonate diol is a specialty polyol used in the production of polyurethane. Polyurethanes made from polycarbonate diol exhibit superior heat resistance, hydrolysis resistance, weatherability, and chemical resistance compared with those based on conventional polyester polyols and polyether polyols.
It is suitable for manufacturing polyurethane resins for synthetic leather, as well as PUD, CPU, TPU, coatings, inks, and adhesives.
