Suzhou 1,3-Propanediol Coolant and Antifreeze Raw Material
1,3-Propanediol is a structurally simple polyol, appearing as a colorless transparent liquid with good hydrophilicity and chemical stability. It is not only widely used in the synthesis of polymer materials such as polyesters and polyurethanes but also commonly serves as a humectant and solvent in cosmetics and personal care products. It can be sourced from either petrochemical pathways or renewable bio-based processes, making it environmentally friendly.
