Product Application
1,4-Cyclohexanedimethanol serves as a key precursor for polyesters. It ranks among the most vital comonomers used in manufacturing polyethylene terephthalate (PET) and polyethylene terephthalic ester (PETE). This compound is applied in synthesizing polyketal copolymers and acts as a diol comonomer in preparing polyester‑carbonates based on 1,3‑propylene‑co‑1,4‑cyclohexanedimethylene succinate.
